E. coli

E. coli strain list - List of the working E. coli strains including genotypes, genetic markers, and alleles.

Non-mutated strains

These strains may not contain any plasmids or resistances, because they should be used for transformation or other experiments.

Storage

Storage of E. coli strains - How to keep E. coli strains.

Glycerol Stock

The glycerol stock is prepared as follow:

900 µL over night culture in LB-liquid medium
900 µL 50 % sterile glycerol

Glycerol is extremely viscous. Hence, use cut off tips to pipette. Glycerol stocks were vortexed to ensure uniformly mixture and shock frozen in N₂ or dry ice. Then, cultures were stored at -80 °C. Do NOT forget to fill in the according GMO S1 construction sheet!

LB-agar

LB-agar plates were prepared as follow:

1% agar (w/v) was added to 1 L LB-broth
LB-agar was autoclaved
LB-agar was poured in plates

The E. coli strains were plated out and stored at 4°C. The plates were renewed every two weeks.
