Week 16: 09/8/08 - 09/12/08
09/8/08
- We prepared 0.5 l of LB + Amp for liquid cultures.
- We infected 9 ml of LB + Amp with 30 µl of Lig.30(3), Lig.31, Lig.22, Lig.13 and two falcon tubes for Lig.a.
- We received 3OC6HSL from Sigma! we resuspended it in ddH2O, we prepared some stocks and stored them at -20°C.
09/9/08
- Glycerol stocks/miniprep for Lig.30(3), Lig.31, Lig.22 and Lig.13.
- Plasmid digestion for:
- Lig.30 (S-P)
- Lig.31 (S-P)
- Lig.30 (X-P)
- Lig.22 (X-P)
- 13 (X-P)
- Run/gel extraction.
- Ligations:
- Lig.31-Lig.30 (="Lig.34")
- Lig.31-Lig.22 (="Lig.35")
- Lig.30-Lig.13 (="Lig.T5" for green fluorescence test)
- We induced one of the two Lig.a overnight culture with 3OC6HSL 1 µM. We incubated the two cultures for 1 hour and then watched TRITC channel at microscope. (We didn't synchronize the two cultures, but performed a qualitative test for luxR mutated protein integrity evaluation).
- Fluorescence test results:
09/10/08
- We transformed/plated ligations. We decided to perform two transformations for each ligation:
- one normal transformation (1 µl of ligation);
- one diluted ligation (1:10)
- We decided to try diluted transformations to have less colonies in the plate and to avoid streaking single colonies plates when colonies are not insulated.
09/11/08
- Plates grew correctly and diluted transformation showed less colonies.
- Colony PCR for Lig.34, Lig.35 and Lig.T5 (4 colonies for normal transformation plates and 4 colonies for diluted transformation plates).
- Gel results:
