Cloning of protein Z DNA to OmpA constructsMichał K.
- Digest of Geneart_Z and pACYC177+OmpA_omega with SacI and NotI (BamHI buffer), pACYC177 was also dephosphorylated with CIAP (3 hr).
- Gel electrophoresis and gel-out of proper bands 220 bp (for Geneart_Z lane) and 4050 bp (pACYC177+OmpA_omega lane).
- Ligation of pACYC177+OmpA_omega and Z fragment DNA (1 hr).
- Transformation of E. coli TOP10 strain with ligation.
- Transformants plating on LB + kanamycin.
Preparation of alpha+A conctructAntoni
- PCR on pKS plasmid containing protein A with
AL+link10+homo2 and AP+NotI
primers (20 cycles, elongation 40 s, annealing temperature 72°C).
- PCR on pUC19 plasmid with
AlphaL+SacI and AlphaP+link10+homo2
primers (20 cycles, elongation 45 s, annealing temperature 63°C).
As a result we got two PCR products (alpha-linker and linker-A) wich will be utilized as templates in next PCR.
- Gel electrophoresis of PCR products and gel-out of proper bands (alpha_linker - 570 bp and linker_A - 470 bp ).
- PCR on alpha+A PCR products with AlphaL+SacI and AP+NotI primers.
- Gel electrophoresis reveal lack of proper 1000 bp band.
