Preparation of constructs with OmpA protein fusions and Cloning of protein Z DNA to OmpA constructs

1. Isolation of plasmids from cultures inocluated on previous day (pCACYC177 + OmpA_alpha and pACYC177+OmpA_Z_omega).
2. Control digest of isolated plasmids with BamHI and SacI (we found good clones for both ligations).

Polymerase Chain Ligation on linker-A and omega-linker

• reisolated PCR product omega-linker - 4 µl
  
• reisolated PCR product linker-A - 13.5 µl
  
• primer OmegaL+SacI_N - 2 µl
• primer AP+NotI_N - 2 µl
