Cloning of truncated fragment of protein A

Piotr

1. Isolation of plasmids from cultures inoculated on previous day.
2. Control digest with SacI and BamHI (BamHI buffer).
3. Gel electrophoresis - proper clones founded for both products of ligation.

Checking if OmpA_omega_A_alpha gives ampicillin resistance

Piotr

Inoculation OmpA_omega_A_alpha from various IPTG concentrations (in mmol/mL) (0, 0.1, 0.25, 0.5, 0.75, 1) into same IPTG concentrations, but with various ampicillin concentrations (in mmol/mL)(25, 50, 75, 100) in ratio: 1:50.

Inoculation of OmpA_omega_A_alpha into various IPTG concentrations: 0, 0.1, 0.25, 0.5, 0.75 mmol/mL (replication is necessary)

Checking OmpA_omega_A_alpha and OmpA_A_alpha expression

Michał L., Ewa, Marcin

1. Separate transformant colonies (transformation from previous day) inoculated to liquid LB with kanamycin.
2. Inoculation of pACYC177+OmpA_alpha and pACYC177+OmpA_omega - liquid LB with kanamycin.
