Plated E. coli
Grace & Norman
Plated E. coli strain DH5-alpha on LB plates made yesterday
- one plate was plated using the hockey puck method for maximum growth
- one plate was plated using the 4-way streak method to isolate colonies
Plates were placed in a 37C incubator for 5 hours then transfered to a 4C incubator for storage. 12 hours then transferred to 26C incubator for growth till Sunday 3pm. (colonies were too small)
Preparation for making competant cells
Grace, Margaret, & Norman
- Autoclaved eppendorf tubes, 10ul, 200ul, 1000uL tips for experiments during coming weeks.
- Made SOB media for growing E. coli DH5-alpha
- Made SOC media
- Made x2 bottles of 12.5X 20mM glucose stock solution (12.5X 20mM = 0.25M)
- Made CMB80 media
(need to filter in detergent free bottle tomorrow)(already filtered into plastic sterile bottle that came with the filtering kit, stored @ 4C) - Made MgSO4 for mixing post-autoclave-separately into SOB and SOC media (forgot to autoclave)
- Made stock of 1 M KOAc
- Made stock of 0.1 N HCl
Discussion
Grace, Margaret, and Norman will come in on Sunday at 3pm to grow up E. coli into exponential phase in preparation for inducing chemical competency.
