Tn5 Transposase Assay
Testing to see whether the Transposase if functional.
Specifically, we varied atc concentration and the time allowed for transposase activity.
Inoculated cells drived from another colony off the iGEM10_020A plate, which didn't undergo co-transformation. We can use these for tests tomorrow.
- Added 10uL of 20% Arabinose (100X) to 1mL of lefty pir+ cells, transformed with iGEM10_020A (no co-transformation occured) at 1:30pm.
- At 2:30pm, will add varying amounts of atc to cells.
- 1uL of 1000X atc diluted 1:10
- 1uL of 1000x atc
- 3uL of 1000x atc
- At 3:30pm, will add 1uL of pBca9145-Bca1144DNA, and allow the transposase to do it's thing for varying amounts of time.
- 3:45pm (15min):Remove 250uL of lysate from each tube and spin down and zymo the supernatant.
- 4:00pm (30min): See above
- 4:15pm (45min): See above
- 4:30pm (1hour): See above (note: less than 250uL was left at this point)
- Transformed each of the 12 zymo purified DNAs into 70uL wild-type mc1061 cells
- incubated for 1 hours
- plated on Amp/Gen plates to grow up overnight
Results
- no colonies on any of the 12 plates
Note: Talked to Terry, and he said one thing we definitely need to vary is the amount of time we give for Transposase expression.
Potential Problem: Used 2YT-Amp for the tubes colored with green sharpie. Hopefully this won't be a problem, since it's sorta the same thing as immediately plating on Amp.

Gibson Assembly of iGEM10_007 and iGEM10_013
Restriction Mapping
In order to save time, I also am running a digest of iGEM10_007 for convenience, and of Bth030 for comparison (because it is about 6kb in length).

Repicking and Colony PCR
- picked 8 colonies each of iGEM10_007 and iGEM10_013
- ran two colony PCRs for each colony using the following oligos:
- for 007
- ca56 + igemTEN4
- igemTEN3+igemTEN8
- for 013
- ca56+igemTEN36
- igemTEN35 + igemTEN20
- for 007
Gel Results
- lane organization:
- lanes 1-16 are eight 007 colonies, odd lanes have primers ca56 + igemTEN4, even lanes have primers igemTEN3+igemTEN8
- lanes 1-16 are eight 013 colonies, odd lanes have primers ca56 + igemTEN36, even lanes have primers igemTEN35+igemTEN20
Results:
There are no distinct bands in any lanes. At this point, I think it best to do another round of 2AB assembly before attempting gibson again for parts iGEM10_007 and iGEM10_013.

Choano Heat/NH4 Assays
- on Friday (3 days ago), I split choanos 1:8 into choano media under the following conditions:
- 25*C(control)
- 37*C incubator
- 37*C with shaking
- 1mM NH4
- 10mM NH4
- results were unconclusive, because even in the control choano density was too low for counts to be reliable, however, here are the counts I did get from PI staining:
- control: 1/4 dead
- 1mM NH4: 12/38 dead
- 37*C incubator:7/17 dead
- I got a fresh culture of MbFb from the king lab so I can redo this experiment starting tomorrow

- I placed this on the plate and selected the program, but failed to hit start, so the wells sat overnight at room temp.
- I restarted the program in the morning, but it is doubtful whether it will yield good results.

iGEM10_013
Picking colonies/Colony PCR
- picked 16 colonies
- oligos used for col PCR: ca56 and igemTen020
- expected band size = 2619
Gel Results
(These are the same gels, but run for different lengths)
Results
- no bands in any of the chosen colonies, however it seems from the short run on the gel that at least one of the primers was binding to to colonies #14 and 16, as there is a large amount of small fragments of DNA
iGEM10_020
Miniprep
Friday's col PCR showed that all the colonies selected for the second col PCR had iGEM10_001 transferred into it. The last 4 lanes appeared to have the strongest bands, so I will choose those colonies to miniprep. I will call colonies represented by lanes 13-16 iGEM10_020 a-d, respectively.
Conor McClune 14:53, 25 June 2010 (EDT)
iGEM10_020
Bacterial lawns grew from both of the transformations from yesterday. Since there is no antibiotic for the correctly Eco/Bam/Bgl transfered product, I will have to do a number of colony PCRs to find one that took up the iGEM10_001 part.
Colony PCR
- oligos: ca56 (fwd) and igemTen22(rev)
- picked 12 colonies from igem10_020 #15 and 4 colonies from igem10_020 #12
Gel Results
- igem10_020 #15
- igem10_020 #12
Results: no insertion in any of the chosen colonies
- I may have forgotten to add DNTPs, which would explain why there are no bands
I repicked 32 more colonies from igem10_020 #15 and ran a col PCR.
Gel Results
- igem10_020 #15 (expected band size: 1803)
- it appears each of the colonies have a plasmid that has iGEM10_001

Manual Assembly of iGEM10_004 and iGEM10_005
- no growth on either of the plates, again
- something must be wrong with ligation or digestion
- however, this was merely a backup for the Gibson Assembly of iGEM10_007, which seems to be working, so there is no need to troubleshoot
Gibson Assembly of iGEM10_007
- sent miniprepped DNA in for sequencing
- I chose colony #3, because the restriction digest band was the brightest
Gibson Assembly of iGEM10_020
- miniprepped colonies 1,3,4,11,12,14,15
- digested with Eco/Bam for restriction mapping
- Results:
Lane 8 (colony #15) is the only one that displays the correct bands
Conor McClune 15:34, 22 June 2010 (EDT)
Manual Assembly of iGEM10_004 and iGEM10_005
- no growth on plates from yesterday, probably because I used only 1uL of ligation mixture for each transformation
- luckily, I kept the ligation mixture, so I redid the transformations, using the remaining ligation mixture for each of the transformations
Gibson Assembly of iGEM10_020
- plenty of colonies on both plates
- picked 8 colonies from each plate, and set up a colony PCR with oligos ca998 and igemTen22
- expected magnified fragment length is 1617
- colony PCR results:
- plate 1(colonies 1-8):
- plate 2(colonies 9-16):
- These colonies look good: 1,3,4,11,12,14,15
Gibson Assembly of iGEM10_007 (2nd Attempt)
- miniprepped growth from yesterdays promising colonies (colonies 2,3,5,7,10,11,13,15)
- created 50uL DNA
- Eco/Bam digested 4uL of each for restriction mapping
- mapping results (expected sizes are 7060 and 3200) :
- Results:
- 7060 band is faint but definitely present in each lane
- 3200band is probably present, but too faint to see, considering it is shorter
- these look good and ready for sequencing confirmation
Conor McClune 15:14, 21 June 2010 (EDT)
Gibson Assembly iGEM10_007, Attempt #2
- cells grew up up on CA plate, no cells on negative control plates (K and Spec), besides the usual few tiny colonies on Spec
- picked 16 colonies:
- for 8 I did colony PCR using ca998 and G00101
- for 8 I did colony PCR with iGEM oligos 1 and 6
- growing up all 16 colonies in 1mL CA LB
Colony PCR
With primers ca998 and G00101 (colonies 1-8):
- expected band size: 9000
- gel picture:
- Results:
- colonies 1,4,6,8 are too short
- colonies 2,3,5,7 show nothing, which is hopeful, since Taq generally cannot copy much larger than 5kb
With iGEM primers 1 and 6 (colonies 9-16):
- expected band size: 2186
- gel picture:
- Results:
- no strong bands
- numerous faint bands in lanes 2,3,5,7 (colonies 10,11,13,15) -- This suggests that something is being read off the primers
- These colonies are promising because the primers are from within the part

Gibson Chemistry
Parts Preparation
DpnI Digestion
I added 0.85 uL NEB2 buffer and 0.5uL DpnI to my Bjh1601 AC PCR product (gel purified) in order to digest all remaining template DNA, which would interfere with the Gibson reacton. The mixture was placed in the incubator at 10:26 and will be ready at 11:26.
- 11.26: Zymo Preparation
- during zymo purification, I accidentally added 200 uL N3j Qiagen Neutralization buffer, instead of PE buffer.
- attempt to recover DNA:
- added 200uL PE to N3/DNA solution
- spun through zymo column in 30sec
- added 200 ADB buffer to solution
- spun through same zymo column in 30 sec
- discarded liquid waste
- spun 200uL PE though zymo column in 15 sec
- discarded liquid waste
- spun 200uL PE though zymo column in 15 sec
- discarded liquid waste
- spun for 90 sec to remove any remaining PE buffer
- discarded waste
- added 17uL H20
- spun into a new eppendorf in 30 seconds
- run on gel
I cut out the band at 3kb and gel purified it. The band is not intense, but it does seem I was able to recover some of the DNA. I gel purified this DNA, but I would prefer to use the product of the below PCR, if it is successful.

- These were the exact procedures I used to originally PCR pBjh1601AC, with one difference: the thermocycler I used (I used the white one on the back wall and ran the 4k55 program under the iGEM folder. Note to future self: do not use programs in this folder). I will repeat this on the same thermocycler
PCR of sbb10
- Continued attempts to PCR sbb10
- double checked oligos on ApE
- created new 1:10 dilutions of oligos igemTen 14 and igemTen16
- in each well: 33uL polymerase MM, 1uL each of diluted igemTen 14 and igemTen16, 0.5 uL sbb10 from well A3 on Parts Plate 1

Wells 1,2 run on program COL2K
Wells 3,4 run on program 2K45
- still no bands appear in the desired 260bp range.
- checked clotho --> the sequence we had entered for sbb10 on our "parts and data" spreadsheet was incorrect
- need to redesign primers igemTen14 and igemTen16
- I redesigned the primers

PCR of B10sbb10, Bjh2294 and pBjh1601AC
- a matching rev backbone primer for pBjh1601AC was found: ss13r
- due to failure of previous pcr attempts for amplifying B10sbb10 and Bjh2294, I decided to try thermocycling at a lower temperature (45*C)
- two well strips:

PDD Part Preparation
Eco/Bam Transfers
- Eco/Bam transfered 1601CA Bjh 2333 L, 1601CA Bjh2348 L,1601CA Bjh2349, and 1601CA Bjh 2331 in pBca1601 AK( we got this from shelley, and had to dilute it by half). We did this because BAC is CAM resistant, so if both parts are Cam resistant, it is possible to lose BAC, which is only single, and not be able to tell. So in the end, we will end up plating our stuff on A/K/C/Spec plates.

Retransformation
- Transforming pB6 BAC into pBca1256-Bjh2343, pBca1256-Bjh2344 and pBca1256-Bjh1934
- adjustments to procedure:
- using only 15uL KCN for 98uL competent cells
- NOT diluting DNA by 10 before adding to cell solution
- For each strain, we split cell/KCN solution into two tubes of 57uL: we added 1μL DNA to one tube and 3 μL to the other tube
- after rescue, entire ~115uL of each solution was plated onto its own plate

- pBca1256-Bjh1934 in MG1655
- pB6 in DH5-alpha
- MG1655
- Bjh2343 in MG1655
- Bjh2344 in MG1655
- scanned and logged these stocks as the first iGEM -80 stocks (created a stock box for -80)
Made Competent Cells
- for pBca1256-Bjh1934 in MG1655,Bjh2343 in MG1655 and Bjh2344 in MG1655:
- added 500μL of overnight-grown culture to 50mL Spec LB in an Erlenmeyer flask
- for MG1655:
- added 1mL of overnight-grown culture to 50mL LB (no AB) in an Erlenmeyer flask (because the solution had been diluted 1:2 with 50% glycerol)
- both flasks put on shaker in lab at 12:00
- 2:00pm
- pBca1256-Bjh1934,Bjh2343 and Bjh2344 (all in MG1655) have all grown up well, but not MG1655 (probably because of the glycerol)
- MG1655 was place back in the incubator
- pBca1256-Bjh1934,Bjh2343 and Bjh2344 solutions were chilled for ten minutes before being transferred to 50mL Falcon tubes and centrifuged for 13 minutes on 4100rpm.
- poured off the supernatant
- added 2.5ml TSS solution to each of the three vials
- made 98uL aliquots into 25 chilled eppendorf tubes for storage (25 tubes for each of pBca1256-Bjh1934,Bjh2343 and Bjh2344)
- pBca1256-Bjh1934,Bjh2343 and Bjh2344 (all in MG1655) have all grown up well, but not MG1655 (probably because of the glycerol)
- Transformed BAC into 1, 2, 3.
- Plated on Cam, Spec plates.
- 3:30
- removed MG1655 from incubator and conducted the procedure above (chilling, centrifuging, resuspending in TSS and aliquoting)
- 100 tubes labeled "1" (for Bjh2343), "2" ( Bjh2344), "3"(pBca1256-Bjh1934), "4"(MG1655 )
- Drops of the remaining solutions in the Falcon tubes were dropped on plates of Amp, Can, Spec, and Chlor as a negative control
Conor McClune 13:52, 8 June 2010 (EDT)
- The five plates from yesterday (shown below) grew up well. We picked two colonies from the following:
- 2343
- 2344
- 1256-1934
- MG1655
- pB6
- The first four of these will mixed with glycerol to be used as competent cells
- Picked Transformed cells from Stage 1 of Assembly of iGEM10_007
- plated on ACK plate to check for cotransformation
- incubated in shaker
- ran colony PCR
Colony PCR
Selected four colonies from each plate. Dipped the pipette tip in PCR tube with 40uL of MasterMix and a well containing 3mL of LB with the appropriate antibiotics, before spreading the pipette tip across a plate with all three antibiotics (to check for cotransformation).

- (with Tahoura)
- Transformed (spec)1256-2343 and (spec)1256-2344 into MG1655. Used minipreps of spec1256-2343 and spec1256-2344 from box and diluted 10x. Mixed 50ul MG1655 with 17.5ul KCN and added 1ul diluted DNA. Incubated for 1hr and plated on Spec. Left in incubator to grow
- Plated pB6 (BAC), place in incubator. Needs to be picked and miniprepped tomorrow.
- Transformed pBca1256-Bjh1934 into MG1655. Used procedure from (1)
- Attempted to enter parts into clotho --> would not save
First step of Manual Assembly
Digestion
Lefty MM added to 9+8, 7+11, 9+20
Right MM added to 7+23, 8+6, 7+5
They should be done incubating at 3:48pm.
Lefty MasterMix (for 4uL miniprep DNA)
- 4uL water
- 1uL of NEB2
- 0.5uL XhoI
- 0.5uL BamH1
Righty MasterMix (for 4uL miniprep DNA)
- 4uL water
- 1uL of NEB2
- 0.5uL XhoI
- 0.5uL BglII
- note: righty digestions had different volumes, which seemed suspicious, so the digestion was repeated with 1uL of each enzyme for 30 min.
Zymo
Means of getting rid of restriction enzymes. Didn't heat kill because BamH1 isn't denatured by heat killing. Eluted with 10uL of H2O. Products are labeled 7+11 L, 9+8 L, 9+20 L.
Ligation:
Followed this protocol with the following amendments:
Mastermix
- 6.5uL ddH2O
- 1uL T4 DNA Ligase Buffer (small red or black-striped tubes)
- 0.5uL T4 DNA Ligase
DNA
- 3uL Lefty vector
- 3uL Right vector
Added DNA to MM at 5:12pm. Will incubate on bench until 5:42pm.
Transformation
- 70uL of each ligation added to cells
- 7+11/8+6 in righty
- 9+8/7+23 and 9+20/7+5 in lefty
