Checking the expression of omp_omega_A_alpha and omp_A_alpha

Piotr

Inoculation of omp_omega_A_alpha and omp_A_alpha with inductor (0,5 mmol/mL IPTG) and negative control without IPTG.

Checking if omp_omega_A_alpha gives ampicillin resistance
Piotr

1. Inoculation of omp_omega_A_alpha into various IPTG concentrations: 0, 0.1, 0.25, 0.5, 0.75, 1 mmol/mL

1. Isolation of plasmids from cultures inocluated on previous day.
2. Control digest of isolated plasmids with BamHI and SacI (we confirmed 4 colonies but A in our constructs turned out to be trunctated and contain only one from two highly similar domains).

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)

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.

Checking for presence of A on the cell membrane
