Lab work
C - The Suppressing Salicylate System
Rehydration of BioBricks
by Fabio
The first step of this Subproject is to rehydrate the following BioBricks. Both provided in the iGEM 2014 DNA Kit Distribution.
- BBa_J61051 - Salicylate promoter + NahR
- BBa_K228001 - RNA suppressor
D - Lemon scent
1 - p cola part 2
by Sean
p cola DNA was extracted in several instances yesterday. Today we attempt to collect all of the DNA and precipitate it.
Protocol
- Add equal parts plasmid DNA and ethanol 100% in a 1.5 microcentrifuge tube.
- If total volume is V, then add V/5 of sodium acetate (initial concentration of NaAc is 3M; we want a final concentration of .3M). Numerical application: Total volume of p cola was 150μl. Hence 150 μl of ethanol 100% was added, as well as 30μl of NaAc 3M. Incubate at -20°C for 30 minutes. (5:20pm - 5:50pm in our case)
- Centrifuge for 10 minutes at 4°C and at 11000g.
- Discard supernatant.
- Add 1ml of ethanol 70%.
- Repeat step 3.
- Discard supernatant. Make tube interior as dry as possible. Tip: use a paper towel on which to lightly tap the rim of the tube. Dry pellet in oven at 37°C. Note: we decided to leave the tube at room temperature and continue tomorrow instead.
- (tomorrow) Resuspend pellet in 30μl H2O milliQ.
