Cloning of protein Z DNA to OmpA constructs

1. Digest of Geneart_Z and pACYC177+OmpA_omega with SacI and NotI (pACYC177 was also dephosphorylated with CIAP)(3 hr).
2. Gel electrophoresis and gel-out of proper bands 220 bp (for Geneart_Z lane)and 4050 bp (pACYC177+OmpA_omega lane).
3. Ligation of pACYC177+OmpA_omega and Z (1 hr).
4. Transformation of E. coli TOP10 strain with ligation.
5. Transformants plating on LB + kanamycin.

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).
