May 2007
May 11
- Autoclaved LB, Agar and Minimal Medium. Made plates with AmpR, KanR and both Amp and Kan. Concentrations used (same for cell cultures):
- Amp: 1uL/mL
- Kan: 10uL/mL
- Cam: 0.8uL/mL (from Elvis' aliquots)
- The receipe for M9 Minimal Medium is in my lab notebook which is in the lab so I'll post it later under the Protocols section. Hopefully we can get the 2007 wiki soon. Horia
May 14
Moved plates from iGEM fridge to fridge on C block (end of hall) Made 100X Yeast extract and 10X Dextrose (for supplementing minimal medium) Prepared CaCl2 and CaCl2/Glycerol 10% solutions for CC procedure of tomorrow Will seed tonight. Horia
May 15
Performed cc procedure with top10 (elvis' home made), bl21 a1 and stble3
Performed seeding procedure on plates from last year: ILS004, duplicate copies of 5mL LB with 50uL KAN; RSE/J40001, duplicate copies of 5mL LB with 5uL AMP; Place in IS overnight
May 16
Transformed cc cells with pUC19 and plated
Repeated seeding procedure as that from previous day did not prove any results (defective shaker?). Both ILS004 and RSE repeated in triplicate with its respective antibiotic. Placed in IS at noon and two samples diluted with LB (100mL to RSE sample and 80mL to ILS004) and placed in the IS overnight. No cell growth.
May 17
Nothing grew on most of the plates. Only 2 colonies on a stble3 plate. Decided the cells were bad because 1. we did not keep them on ice while we transported them etc. and 2. some cells waited a long time on ice because we had to do sequential centrifugations (not enough of one kind of tube). Removed from incubator at night and placed in the fridge.
Susan, Avi and Jimmy seeded cells again for Friday. BL21, Top10 and STBLE3 repeated in triplicate in 5mL LB and placed in SI overnight.
May 18
Performed cc procedure.
May 22
Made LB for Seeding procedure from 15.5g of solid LB to 500ml of water - x3.
Performed transformation of competent cells with pUC19 (Top 10 and Stble 3) and BL21 with PGFP and Amp antibiotic to validate their quality.
For the transformation procedure, used LB instead of S.O.C. Medium, due to its unavailability, then spread the cells on Agar gel plates with Amp and LB and placed in SI overnight.
Made some additional Agar gel plates with Amp, which were kept in the freezer for future use.
