Note: NotI is only 50% efficient in Buffer 2 so I also set up a sequential digest (Nick said that one time that anything under 100% for NEB enzymes is unreliable). Also, both the PCRed rdm lib samples above and below came from the first PCR reaction (tube labeled 1 and lane one from the [[IGEM:Harvard/2007/GeorgeXu/08142007colonypcrgx|gel]]).

====Miniprepping AIDA-1/pet29b+====
+
-
Miniprepped the AIDA-1 (~150 ng/uL for all three samples; curves looked good)
+
-
 
+
-
====PCRing Random Library====
+
-
Realized we don't have NotI enzyme so set up a PCR reaction for the random library + AIDA:
+

|}
+
-
Both primers can be found in the -20dC freezer in the small room in a box labeled with green tape (something like "Mike Strong Plasmids for iGEM 2007"). These are primers for the 15mer library.
+
-
 
+
-
I used the "rdm lib pcr AIDA" (or something like that) program on the grey machine near the entrance of the big room. The program steps are:
+
-
# 95dC for 04m00s
+
-
# 35 loops of:
+
-
## 95dC for 00m15s
+
-
## 55dC for 00m30s
+
-
## 68dC for 02m15s
+
-
# 68dC for 15m00s
+
-
# 4dC forever
+
-
 
+
-
After the PCR, I ran a [[IGEM:Harvard/2007/GeorgeXu/08142007colonypcrgx|gel]]. The bands looked the correct size and were relatively bright.
+
-
 
+
-
===9/14/07===
+
-
====Growing Liquid Cultures (AIDA-1/pet29b+)====
+
-
Grew up 3x4.5mL of AIDA-1 in LB kan from Perry's frozen stock (loc:Perry's box in the -80dC). Tubes were labeled something like "AIDA-1/pet29b+."
+
-
 
+
-
===8/18/07===
+
-
====Rdm lib + AIDA construction====
+
-
#AP treated 50 µL of AIDA1 cut with NotI/NheI in pet29 with 6 µL AP buffer and 4 µL AP
+
-
#Clonewelled the samples
+
-
#Vacufuged and PCR purified the samples
+
-
#Nanodropped and set up three ligation reactions
+
-
##PCR digest 1 + cut AIDA
+
-
###PCR digest - 30 µL of 33.8 ng/µL lyophilized and resuspended in 13.5 µL, used 7 µL
+
-
###cut AIDA - 47 µL of 37.3 ng/µL lyophilized and resuspended in 9 µL, used 3 µL
+
-
##PCR digest 2 + cut AIDA
+
-
###PCR digest - 32 µL of 45.1 ng/µL lyophilized and resuspended in 19.4 µL, used 7 µL
+
-
###cut AIDA - 47 µL of 37.3 ng/µL lyophilized and resuspended in 9 µL, used 3 µL
+
-
##PCR digest 3 + cut AIDA 
+
-
###PCR digest - 32 µL of 45.7 ng/µL lyophilized and resuspended in 19.4 µL, used 7 µL
+
-
###cut AIDA - 47 µL of 37.3 ng/µL lyophilized and resuspended in 9 µL, used 3 µL
+
-
 
+
-
====Re-electroporating tagged Single Cells + T02 his====
+
-
I had to miniprep more JT because we used up the plasmid preps from last time
+
-
#JT DNA into AIDA his cells (from Steph's fridge liquid cultures)
+
-
#JT DNA into AIDA+strep cells (from Steph's fridge liquid cultures)
+
-
#RACE DNA into AIDA+strep cells (from Steph's fridge liquid cultures)
+
-
#RACE DNA into AIDA+strep cells (from Steph's fridge liquid cultures)
+
-
#AIDA+his DNA (from Mike's iGEM box) into T02 cells
+
-
Plates should be in incubator
+
-
 
+
-
====Checking Tagged Receivers====
+
-
*Round 1
+
-
**Colony PCRed the RAE+his, RAE+strep, and T02+strep (the T02+his plate was empty).
+
-
**Unfortunately, there are only SybrSafe E-gels left, so no gel picture. Gel summary below (basically RAE+strep 2 and T02+strep 2-5 worked)

*Round 2
+
-
**Basically I redid RAE+his 1-3 and then streaked three more colonies to get RAE+his4-6. I also checked RAE+strep 2 and T02+strep 3-5 with the T7 promoter/terminator primers. Note I have two wells of RAE+strep 2 because I distrust (is that a word?) colony PCR.
+
-
**Results were good. The RAE_strep 2 and T02 strep3-5 check out completely. It appears that RAE+his 3 also checks out. I've set up the T7 PCR reaction for that have it sitting in the black PCR machine on Stephanie's bench.

====Other====
+
-
*Finally streaked those liquid cultures of the constructs we sequenced.
+
-
*Streaked the liquid culture of pAC-luxGFP (Voigt construct)
+
-
*miniprepped the pAC-luxGFP
+
-
*poured several LBamp+kan plates. They should be labeled with black sharpie on the broad circular face of the plate.

====Colony PCR of RACE (new)====
+
-
RACE #1-3 are correct.

[[IGEM:Harvard/2007/GeorgeXu/08142007colonypcrgx|Gel]]
+
-
 
+
-
===8/13/07===
+
-
====Fluorescent Microscopy of RACE====
+
-
I picked from six samples from three plates of RACE and dipped into 10 µL of PBS:
+
-
*RACE 37dC (new) - the new RACE transformation plate
+
-
**Center of the colony (fluorescent)
+
-
**Edge of the colony (nonfluorescent)
+
-
*RACE 37dC (old) - the RACE plate the old transformation
+
-
**fluorescent cells
+
-
**nonfluorescent cells
+
-
*RACE - the original RACE transformation plate
+
-
**Center of the colony (fluorescent)
+
-
**Edge of the colony (nonfluorescent)
+
-
 
+
-
Microscopy Results:
+
-
*For the most part, the expected nonfluorescent cells are nonfluorescent and the fluorescent cells are fluorescent. However, it seems that the original plates are exhibiting stronger fluorescence than the new transformation plates which is opposite of what Nick, Harris, Bill and I observed in the transformation plates
+
-
*I need to fix my protocol for preparing slides because I have problems with the ends of my slides drying in and some of my samples were very dilute.
+
-
*These RACE cells didn't have the filament problems like the last RACE I grew. I'm going to retry the RACE+OHHL and RACE overnight to see if I can get some positive results.

====Colony PCR of JT + confirm Master Plate====
+
-
JT's are whacko, the Master Plate constructs are correct. We need to re-transform JT into BL21.
+

====Frozen Stock Part 1====
+
-
Perry and I made frozen stocks of some stuff.
+
-
 
+
-
===8/09/07===
+
-
====Mixed Cultures with same OD====
+
-
I had a culture of S23I07 diluted to OD=0.057 and a culture of RAE diluted to an OD=0.059. I made a 1:1, 10:1, and 100:1 combined culture (with more of the RAE). I also had a culture of RACE that I induced with ~1 mM.
+
-
 
+
-
I grew these for about three hours and then checked them in the plate reader and the fluorescent microscope.

Fluorescent Microscope Results #1:
+
-
*Not too much to say here, it seems that the cells haven't grown enough because we don't see much fluorescene yet and the OD's are still pretty low
+
-
*One thing of note: the RACE is abnormally filamentous. Something is wrong...
+
-
[[IGEM:Harvard/2007/GeorgeXu/08082007fluormicro1|Fluorescent Microscopy Pics 1]]

I grew the samples for another two hours and then checked them again in the plate reader and the fluorescent microscope.

Fluorescent Microscope Results #2:
+
-
*The RFP fades RIDICULOUSLY fast. The fluorescence fades to black in a couple of seconds.
+
-
*The GFP in the mixed cultures is pretty good, the RFP is almost invisible. This could be the result of the RFP folding time and the fact that the RFP fades RIDICULOUSLY fast. Seriously, like, Nick and I basically had to say "1...2...3... GO!" to make sure we got the picture on time

I also checked the cultures under the fluorescent microscope:
+
-
*The S23I + RAE sample showed a lot of red colonies and a very small number of green colonies.
+
-
**Maybe the red colonies are just much better competitors? It could also be because I didn't start with equal OD's. I'm going to redo this tomorrow.
+
-
*The RAE works surprisingly well. By itself, it has a pretty good OFF and the induced with OHHL was brightly fluorescent.

-
 
+
-
The only difference is that the Minipreps turned out a lot better, giving nanodrop values of >130 ng/µL. Also, I stupidly transformed into Top10F' instead of Top10.

===7/29/07===

====Colony PCR of luxpR Round 1 Take 2====
+
-
I colony PCR'ed the colonies from the transformation plates from last night. The plates were a little better, with around 10 colonies each. I only got *i think* the [http://parts.mit.edu/registry/index.php/Part:BBa_C0061 C0061]<[http://parts.mit.edu/registry/index.php/Part:BBa_I13504 I13504] to work. Also, the five bands that should be [http://parts.mit.edu/registry/index.php/Part:BBa_R0062 R0062]<[http://parts.mit.edu/registry/index.php/Part:BBa_A340620 A340620] are all about the size of [http://parts.mit.edu/registry/index.php/Part:BBa_R0062 R0062] so I'm going to redo the construction tomorrow.

-
**Two colonies
+
-
So I colony PCR'ed them and then froze the result (no gel running today, folks).
+
-
===Religating and Transforming===
+
-
I re-ligated and transformed some leftover DNA from last night:
+
-
 
+
-
*[http://parts.mit.edu/registry/index.php/Part:BBa_R0062 R0062]<[http://parts.mit.edu/registry/index.php/Part:BBa_A340620 A340620]

-
 
+
-
Finally, I transformed the constructs into Top10 cells.
+
-
 
+

====Clonewell, Vacufuge, Ligate, Transform====
+
-
I clonewelled, vacufuged, and then ligated the following:

+
-
 
+
-
Finally, I transformed the constructs into BL21 cells.
+
-
 
+
-
====Dephosphorylating the Vectors====
+
-
I dephosphorylated the [http://parts.mit.edu/registry/index.php/Part:BBa_R0062 R0062] and [http://parts.mit.edu/registry/index.php/Part:BBa_C0061 C0061] with Antarctic Phosphotase and then heat inactivated them for 10m at 65dC.

====Overnight Plate Reader Growth Curve Results====
+
-
I set up a plate reader as follows. The numbers after the label indicate starting OD. Note: Our plate reader seems to have trouble reading OD's around 0.1, so I'm not completely sure if the 0.1 values are accurate. I took the lower OD readings in the OD machine in the small room, so I'm pretty confident about those.

Results:
+
-
* Starting at OD~0.1 or OD~0.04 it took the samples around 2 1/2 hrs to read OD~0.3 and around a total of 6 hrs to hit stationary phase
+
-
*Starting at OD~0.003, it took the samples around 4 hours to reach OD~0.3 and around a total of 7 hours to hit stationary phase
+
-
* There didn't seem to be a big difference between starting at OD~0.1 vs OD~0.04. Of course, this could be due to the fact that I took the OD reading for the OD~0.1 samples in the plate reader, which is inaccurate in that range.
+
-
* Overall, the samples grew at pretty much the same rate. There appears to be at most a 45-60 min lag between different constructs, but this could be due to variations in starting OD.
+
-
* The blank LB samples were interesting. They were pretty much flat and low until around 8 hrs in, then they grew exponentially to around OD~1. This seems to indicate that there were very low levels of contamination in these LB wells. I added LB+amp to these wells, so the contamination is probably coming from our own constructs. I don't know if this contamination was present when I loaded the wells or somehow there was cross-well contamination during the reading period.

====Mike's Agar Plate Experiment====
+
-
Perry and I carried out a preliminary test of Mike's Plate Reader Experiment.
+
-
Protocol:
+
-
# Pipet 200 µL of overnight cultures of [http://parts.mit.edu/registry/index.php/Part:BBa_T9002 T9002] and spread onto LB agar plates.
+
-
# Let the plates sit at room temperature to allow the bacteria to soak in. (We let it sit for about 20 minutes)
+
-
#Pipet in 10 µL of one of each of the following into the middle of each plate.
+
-
## Overnight culture of [http://parts.mit.edu/registry/index.php/Part:BBa_S03623 S03623] > [http://parts.mit.edu/registry/index.php/Part:BBa_I13507 I13507]

+
-
## 2 µM OHHL
+
-
We did duplicates because we took from two different overnight cultures, one that was obviously red and one that was not obviously red.
+

+
-
====Ligating and Transforming the RP-JT and FluorSwitch====
+
-
Perry and I performed the following ligations and transformations:

+
-
into BL21
+
-
 
+
-
We decided not to do the other ligations and transformations because we found out that we already have a [http://parts.mit.edu/registry/index.php/Part:BBa_S03623 S03623] <[http://parts.mit.edu/registry/index.php/Part:BBa_E0240 E0240] and we were colony PCR'ing a  [http://parts.mit.edu/registry/index.php/Part:BBa_S03608 S03608]<[http://parts.mit.edu/registry/index.php/Part:BBa_E0240 E0240].

-
====Clonewell for RP-JT and FluorSwitch====
+
-
I clonewelled and vacufuged all the [[User:GeorgeXu#Digest_for_RP-JT_and_FluorSwitch|digests]] I did earlier in the day. The band for [http://parts.mit.edu/registry/index.php/Part:BBa_J23039 J23039] >[http://parts.mit.edu/registry/index.php/Part:BBa_T9002 T9002] was almost invisible.

====Sequencing the F2620 and E0240====
+
-
I prepared a sequencing order for [http://parts.mit.edu/registry/index.php/Part:BBa_F2620 F2620] and [http://parts.mit.edu/registry/index.php/Part:BBa_E0240 E0240].

-
I dephosphorylated JT with Antarctic Phosphotase (1 hr 37dC) and then heat inactivated at 65dC for 10 min.
+
-
===7/20/07===
+
-
====Clonewell and Vacufuging the RP and JT parts====
+
-
I clonewelled the leftovers from the RP and JT digests and then vacufuged and resuspended in 20 µL of nuclease free water. This was done in order to try rebuilding the constitutive tetR+JT construct.
+
-

====Liquid Cultures of 2 cell system and RFP+JT====
+
-
I grew liquid cultures of the 2 cell system and the RFP+JT in preparation for plate reader experiments tomorrow.

None of the colony PCR's gave the correct size DNA piece.

====Miniprep the RFP+JT====
+
-
I miniprepped the RFP+JT sample (originally for transformation in Top10 because BL21 expresses LacI, but we decided that we liked the idea of inducible RFP).
+
-
 
+
-

-
====Liquid Cultures====
+
-
I grew liquid cultures of the "correct" RFP+JT colony resulting from the colony PCR.

-
====Colony PCR of the tetR+JT and RFP+JT constructs====
+
-
I colony PCR'ed the teR+JT and RFP+JT constructs.
+
-

Results: Only one colony seemed correct. It was one of the constitutive RFP+JT parts.

====Clonewell and Vacufuge of the R-P constructs====
+
-
I clonewelled and vacufuged the R-P constructs and the JT. Unfortunately, I forgot to include the JT with the initial clonewell, so I ended up having to fish the very nasty clonewell out of the garbage (there was a piece of gel on it and chunks of gel were stuck in some of the wells). I used the last two wells (which were thankfully somewhat clean) for ladder and the JT. Unfortunately I ran into a few problems. First, the JT is about 2800 bp and the plasmid is about 2000 bp. The two bands on the clonewell were pretty close and it was difficult to separate the two bands sometimes. Second, the gel stopped running after a while. I noticed bubbles forming along the edges of the gel and whenver I pressed "Go," the gel would make an unhappy beeping noise and blink yellow, so I just stopped running the clonewell

====Liquid Cultures====

I grew up liquid cultures of the following constructs, which come from the colony PCR's that Stephanie did in the morning:

+
-
 
+
-
The Upper/Lower Right is due to the fact that the colony PCR plate had duplicates of those colonies and it was unclear which colony was correct (at least, the PCR and gel was correct). So, I took both samples and labeled one as coming from the upper right of the plate (when viewed with the handwriting going the correct way) versus lower right.

+
-
====Dephosphorylation of J04450 and JT====
+
-
I used Antarctive Phosphatase to dephosphorylate the [http://parts.mit.edu/registry/index.php/Part:BBa_J04450 J04450] and the [http://parts.mit.edu/registry/index.php/Part:BBa_J23039 J23039]>[http://parts.mit.edu/registry/index.php/Part:BBa_T9002 T9002]. I also heat inactivated at 65dC for 15 minutes.
+
-
 
+
-
After doing this, I was informed by Perry that I shouldn't dephosphorylate the insert. ARGH! I'll need to regrow, miniprep, and digest the JT.

I vacufuged the samples digested on 7/12/07 for a total of about 3 hours. I then resuspended the samples in about 20 µL of nuclease-free water. I nanodropped them, but the numbers were ridiculously high (~200 ng/µL) and the curves looked awful. Note to self: never Nanodrop gel extraction again.

====My First Clonewell====
+
-
#Get iBase+Clonewell gel. Remove gel (leave the comb!) and place into iBase.
+
-
#Pre-run (Mode 0) for two minutes while the comb is still in the gel
+
-
#Take out comb, load each well in top row with 20 µL samples, the middle well with ~10 µL ladder, and the bottom row wells with 20 µL nuclease-free water
+
-
#Run the gel with (Mode 5: Run Clonewell), watch the bands and stop the gel when your desired band hits the dashed line above the bottom row of wells
+
-
#With the gel stopped, fill the bottom row wells with nuclease-free water.
+
-
#Run the gel again. When you see the band starting to enter the well, take out the sample in the well and put into clean labeled centrifuge tube. Then refill the well with 20 µL nuclease-free water and continue running the gel.
+
-
#Repeat this procedure until you get enough sample. If the band runs past the well, you can use Mode 6: Reverse Clonewell to make the band move back into the well
+
-
 
+
-
So basically, I did this for the stuff that was digested (see immediately below) and I ended up with a lot of water, so I am going to vacufuge the results tomorrow.

====Perry's E-gel====

I ran an E-gel for Perry's colony PCR.
+
-
#Take out E-gel (leave comb in) and put in one of the bases. NOTE: One of the red bases has a faulty contact which requires covering by aluminum foil to work correctly.
+
-
#Pre-run the gel for 2 minutes. (Press and hold either 15min or 30min on the red bases or Mode 0 on the gray bases)
+
-
#When the pre-run is finished, press any button to stop the beeping.
+
-
#Load 10 µL of nuclease-free water and 10 µL of ladder into the first well. Then 10 µL nuclease-free water + 10 µL sample into every other well. If there are empty wells, put in 20 µL of nuclease-free water into the empty wells. NOTE: Nick mentioned this and it is a pretty good idea. Put the ladder in the middle well or if there are empty wells, put ladder in the end empty wells. This way, it is easier to compare, especially if the bands bend.
+
-
#Run the E-gel for 30-min (Press 30min on the red bases, or run Mode 1 - changing the time if necessary)
+
-
#When the run is done, press any button to stop the beeping. Use the UV machine in the small room to visualize the gel.

It confirmed that P0140 and P0340 were correct. However, I don't think his GFPmeks turned out very well.

The plan was to dilute the above samples to about 40-60 ng/µL and I did the dilutions, but I stupidly ended up using the stock instead of the dilution so our samples had a LOT more DNA than we had planned. Eh, it still ended up working out.

-
[[IGEM:Harvard/2007/Laboratory_Notebooks/Quorum_Sensing/Week_2#Growth_of_colonies_in_liquid_cultures|Protocol]]
+
-
 
+
-
Stephanie and I grew liquid cultures of the following parts:
+
-
*[http://parts.mit.edu/registry/index.php/Part:BBa_I13263 I13263]
+
-
*[http://parts.mit.edu/registry/index.php/Part:BBa_I13273 I13273]

+
-
*[http://parts.mit.edu/registry/index.php/Part:BBa_T9002 T9002 (-)]
+
-
Also, Stephanie left the T9002 (+) sample incubating with 1000 nM OHHL to serve as a comparison to J37015.
+
-
 
+
-
====Colony PCR of Ligated Parts====
+
-
[[IGEM:Harvard/2007/Protocols#Colony_PCR.2Fplate_streak|Protocol]]
+
-
 
+
-
Stephanie, Perry, and I colony PCR'ed the parts that they ligated the week before.
+
-
 
+
-
See [[Shlo/notebook#7.2F9|Stephanie's notebook]] for results.

-
===6/29/07 FACS DAY (I13263)!===
+
-
====FACS-related====
+
-
*8:30 AM - Stephanie and I took the OD of the overnight cultures.
+
-
**Results - 1.785, 1.793, 1.780
+
-
*9:15 AM - Stephanie and I performed first dilution (growing the 4 hr induction cells). Unfortunately, we didn't dilute correctly...
+
-
**1:40 dilution: 50 µL liquid culture + 148 µL LB broth + 2 µL ampicillin
+
-
**1:80 dilution: 25 µL liquid culture + 173 µL LB broth + 2 µL ampicillin
+
-
**1:100 dilution: 20 µL liquid culture + 178 µL LB broth + 2 µL ampicillin
+
-
*10:30 AM - Oopsie, we realized we didn't dilute 1:40, etc.; instead, we had actually diluted 1:4, etc. We measured the OD's of these incorrectly diluted samples and rediluted the samples. Note that in order to measure the OD, we diluted samples 1:100, measured the OD, and multiplied the measured OD by 100 to give us our measurement for the actual sample.
+
-
**1:4 sample OD = 3, redilute 1:100 giving us a sample of about OD=0.03
+
-
**1:8 sample OD = 1.8, redilute 1:30 giving us a sample of about OD=0.05
+
-
**1:10 sample OD = 1.3, redilute 1:100 giving us a sample of about OD=0.01
+
-
**Also, we diluted 1:40, 1:80, and 1:100 2 mL samples from the overnight stock to grow as our 2 hr induction cells
+
-
*11:00 AM - I diluted the stock solution 1:10,000 and 1:1,000,000 in 100 µL 200-proof ethanol to give a 97 µM and 97 nM solution.
+
-
*11:30 AM - Stephanie and I diluted 1:40, 1:80, and 1:100 2 mL samples from the overnight stock to grow as our 1 hr induction cells
+
-
*12 noon - Stephanie and I took the OD of the 4 hr induction cells
+
-
**4 hr induction cells, 1:40: 0.2
+
-
**4 hr induction cells, 1:80: 0.2
+
-
**4 hr induction cells, 1:80: 0.1
+
-
Since each of these were about 2 mL samples, we didn't have enough sample to have 2 mL cuvette samples. Instead, we used 1mL of cells with 10.5 uL HSL. 2 samples were taken from the 1:40 first dilution (8:30am) - used for the 10 and 100nM HSL runs - and 1 from the 1:80, used with 1nM HSL.
+
-
*1:30 pm - Took OD of the 1hr and 2hr samples + Induce the 2 hr samples
+
-
 
+
-

+
-
[[IGEM:Harvard/2007/Laboratory_Notebooks/Quorum_Sensing/Week_2#Growth_of_colonies_in_liquid_cultures|Liquid Cultures Protocol]]
+
-
 
+
-
Perry and I transformed and prepared liquid cultures of the following parts:
+
-
*[http://parts.mit.edu/registry/index.php/Part:BBa_S03623 S03623]
+
-
*[http://parts.mit.edu/registry/index.php/Part:BBa_S03608 S03608]

===6/28/07===
+
-
====Resuspending the HSL stock====
+
-
I took the 25 mg of [http://www.sigmaaldrich.com/catalog/search/ProductDetail/FLUKA/09945 N-Butyryl-DL-homoserine lactone] and resuspended in 1.5 mL of 200-proof ethanol. I then put the tube in the Quorum sensing box in the freezer at Stephanie's bench.
+
-
 
+
-
This was done in preparation for inducing the FACS samples on 6/29/07.
+
-
====Digestion of F1610: Part Two====
+
-
Stephanie ran another F1610 digest with
+
-
#2.5 µL Buffer 2
+
-
#0.5 µL BSA
+
-
#0.5 µL XbaI
+
-
#0.5 µL PstI
+
-
#21 µL F1610
+
-
 
+
-
Basically it is the same as [[User:GeorgeXu#Digestion_of_F1610_.28XbaI.2C_PstI.29|the previous digestion]] except we now have 21 µL vs. 15 or 6 µL of DNA. This was done because the Clonewell of the F1610 that Perry and I ran had an almost invisibly faint band corresponding to the F1610. Where did all the DNA go?
+
-
====Grow Liquid Cultures of I13263====
+
-
[[IGEM:Harvard/2007/Laboratory_Notebooks/Quorum_Sensing/Week_2#Growth_of_colonies_in_liquid_cultures|Protocol]]
+
-
 
+

Stephanie and I grew I13263 in preparation for the FACS on 6/29/07.
+
-
====Sequences====
+
-
Perry checked the sequences that we got back from Genewiz<br>
+
-
Results<br>
+
-
* [http://parts.mit.edu/registry/index.php/Part:BBa_F1610 F1610] (something is very wrong...)
+
-
** The actual part is 798 bp, we got back a sequence ~300 bp
+
-
** The sequence contains the terminator and some random junk after it
+
-
* [http://parts.mit.edu/registry/index.php/Part:BBa_I13263 I13263] (w00t)
+
-
** The first and last ~650 bp are perfect.
+
-
* [http://parts.mit.edu/registry/index.php/Part:BBa_I13272 I13273]

-
** !!!!add something here
+
-
!!!!upload the sequences?

-
Results
+
-
 
+
-
[http://parts.mit.edu/registry/index.php/Part:BBa_F1610 F1610] is about 800 bp. There is an almost invisibly faint band at 800 bp. What happened to all the DNA? We need to run it again
+
-
 
+
-
====Transformation of Additional Parts====
+
-
[[IGEM:Harvard/2007/Protocols#Transformation|Protocol]]
+
-
 
+
-

====Digestion of F1610 (XbaI, PstI)====
+
-
 
+
-
Mix 1:
+
-
#2.5 µL Buffer 2
+
-
#0.5 µL BSA
+
-
#0.5 µL XbaI
+
-
#0.5 µL PstI
+
-
#15 µL F1610 (168 ng/µL)
+
-
#6 µL Nuclease-free water
+
-
Mix 2:
+
-
#2.5 µL Buffer 2
+
-
#0.5 µL BSA
+
-
#0.5 µL XbaI
+
-
#0.5 µL PstI
+
-
#15 µL Nuclease-free water
+
-
#6 µL F1610 (168 ng/µL)
+
-
 
+
-
Perry and I ran two digests of F1610 with different amounts of DNA. The plan is to gel extract and ligate with the promoters that Perry has transformed.

====Transformation of I13263====
+
-
[[IGEM:Harvard/2007/week_1#Transformation_protocol|Protocol]]
+
-
 
+
-
Stephanie and I transformed 1 µL of the I3263 that we midiprepped into 30 µL of BL21. We then plated them onto agar+ampicillin plates. We eventually want to carry out a test experiment by inducing the I3263 with different concentrations of HSL to test and possibly start characterizing the part.

-
 
+
-
We ran this protein gel to see if the OmpA1+His, OmpA1+Strep, OmpA2+His, and OmpA2+Strep was actually expressed. Also, we wanted to see if there was any difference between the immediate induction, delayed induction, and no induction.
