Preparation of constructs: OmpA_alpha and OmpA_omega #2

Piotr, Weronika

It's the second attempt to clone OmpA_alpha and OmpA_omega to pACYC177, but now thank's to Paweł we've got both fusions on pET15b.

  1. Digest of confirmed clones of pET15b+OmpA_alpha and pET15b+OmpA_omega with NdeI and BamHI (Tango 2x buffer).
  2. Digest of pACYC177 plasmid with NdeI and BamHI (Tango 2x buffer), dephosphorylation with CIAP.
  3. Gel electrophoresis of digested plasmids and gel-out of proper bands (OmpA_alpha- 1000 bp, OmpA_omega - 800 bp).
  4. Electrophoresis of gel-out products.
  5. Overnight ligation of pACYC177 and OmpA_alpha.
  6. Overnight ligation of pACYC177 and OmpA_omega.

Cloning omega-A fusion on pKS (second attempt)

Michał L., Ewa, Marcin

We have just received corrected version of omegaP-link10-homo2 primer. Let's hope this time everything will be fine. We are repeating the PCRs:
