Testing Thermoinducible Lac System
Restreaked Plates of P92-3 in S1 7/21
Restreaked P93 (1:3), P92a, and P93b--all successfully transformed in S1--to detect YFP at 30 and 40 degrees.
Results 7/22
S1 P93 (1:3), P92a, and P93b plates grown at 30 and 40 degrees failed to demonstrate any difference in YFP expression. Both expressed very low, if any, YFP.

Housekeeping
Making Competent Cells 7/22
Made ~600 100uL (some were 200 uL, indicated by green dot on top) aliquots from 1L of culture. Done as per Jason's lab's protocol.
New cells seem to work, but tested heatshock times with puc19 7/25/08.
Ligations 07/22
- Attempted to ligate p40 cut with SP (w/ RBS) to mtrB cut with XP. Thus far, the ligation has not worked.
Recombination Update 07/22
- Thus far, none of the attempts to extract flanking regions from the genomic DNA have worked. We are troubleshooting this now and will run positive controls with known DNA samples to check the efficiency of our Phusion Polimerase.
07/23 Ligations/Transformations
- Ligated p40 cut SP with mtrB cut XP at 2:3, 1:2, 1:4, 1:5, 1:6, positive control is uncut p40, negative control (to test Amp plates) is p29 (Kan)
Ligations 07/24
We ligated p75a w/ p63 w/ a ratio of 4ul p63:1ul p75a
Transformed into new dh5α competent cells w/ volumes of 1, 3, and 5uL, using Jason's new protocol. As a control transformed 1uL of pUC19.

400 μL (8 reactions) each of P1 and P3 were set up using a doubling of above reaction mix. The reaction conditions were the same except that annealing temperature was 45°C, and cycles occur 40 times.
100 μL (2 reactions) each of HO-pcyA and P51 MIT were set up using above reaction ratios. 40 cycles were performed with 55°C annealing temp and 1:35 extension time.
Products will be gel purified along with products from optimization PCRs.

Ligations with purified digest fragments 07/23: mtrB+RBS, CDF into pSB3K3
We ligated
- P97 and mtrB BB
- P3 and CDF
We used three different ratios of insert to vector for the ligation: 6/2, 5/1, 7/1.
We used 5 μL of the ligation to transform TOP10 cells and 5 μL to transform the new DH5α cells. We also used 1 μL and 3 μL to transform DH5α. We used pUC19 (1 μL) as a positive control to test the efficacy of the new DH5α cells.
We used Jason's protocol to transform the new DH5α cells:
- Thaw cells by resting tubes on ice
- Then add DNA and mix by swirling with the pipette tip
- Incubate the cells with DNA in ice for 10min
- Heat shock at 42C for 2min
- Then incubate in ice for 2-5min
- Add 500-700ml LB (or SOC) and incubate + 250rpm shaking for 1hr at 37C
- Plate

Ligations with purified parts and PCR products 07/26
Ligations were performed using standard protocol. New homemade cells were heat shocked for 40s, and incubated in 200μL SOC for 1 hour prior to plating on prewarmed plates. Vectors were dephosphorylated with Antarctic Phosphatase as per NEB's protocol.

Cultures for miniprep
When possible, 2 non-fluorescent colonies were picked from each plate (fluorescence in the P1/P3 derived plasmids indicates P1/P3 vector religation).
RE digests of minipreps 07/26
We digested
- P46 with NheI
- P90+49 and P90+48 with XbaI and SpeI
- When these parts are combined, we will have a plasmid with the CDF origin (CDF+Amp and CDF+Cm in the base vector)
- P3+17 and P1+17 with EcoRI and XbaI
- We can add the high and low constitutive promoters to give us the complete Tet system (without GFP) in a p15A vector
- P39+51, P38+51, P38+17 with XbaI and PstI
- We can put these parts into P1 and P3 to give us the complete Tet and Lac systems in a p15A vector
