Preparation of constructs with OmpA protein fusions
Michał K.
PCR on pB30D plasmid with
OmpaL_N and OmpaP_link
primers (15 cycles, elongation duration 45 s, annealing temperature 63°C).
PCR on pUC19 plasmid with
AlphaL_link and AlphaP_XB
primers (20 cycles, elongation duration 45 s, annealing temperature 63°C).
PCR on pUC19 plasmid with
OmegaL_link and OmegaP_EPB
primers (20 cycles, elongation duration 30 s, annealing temperature 58°C).
As a result we got three PCR products: OmpA_linker and two fragments of TEM1 beta-lactamese: linker_alpha and linker_omega.
Gel electrophoresis of PCR products and gel-out of proper bands (OmpA_linker - 500 bp, linker_alpha - 600 bp and linker_omega - 350 bp).
Electrophoresis to estimate the concentration of isolated DNA.
