Preparation of constructs with OmpA protein fusions

  1. Colony PCR on colonies from plates with transformations pACYC177+OmpA_omega and pACYC177+OmpA_alpha Primers used: OmpaL_N and OmpaP_link
  2. Confirmed transformant colonies inoculated to liquid LB with kanamycin

Preparation of construct pKS with A protein
Michał L., Marcin:

  1. Gradient PCR (achieving multiple copies of gene coding A protein):
    template DNA pDRIVE-TAPtag - 1 µl
    primer <a href="https://2008.igem.org/Wiki/Team:Warsaw/primers#AP+NotI_N">AP+NotI_N</a></html> - 2 µl
    primer AL+SacI_N - 2 µl
    Pfu buffer with Mg2+ - 5 µl
    10 mM dNTPs - 1 µl
    Pfu Turbo polymerase - 0.5 µl
    H2O - 38.5 µl

    Program:
    1. 94°C, 3 min
    2. 94°C, 30 sec
    3. 62 to 74°C, 45 sec
    4. 72°C, 45 sec
    5. Repeat of elongation step 25X
    6. 72°C, 10 min
    7. Hold at 4 °C
  2. Gel electrophoresis of PCR product.
  3. Isolation of proper band (470 bp) from the gel.
  4. Overnight digest of isolated PCR product and pKS vector with NotI and SacI; to the reaction mix with pKS added 0.5 µl of CIAP.

Preparation of construct pKS with A protein

  1. Colony PCR on colonies from plates with transformations pKS-A
    Primers used: AL+SacI and AP+NotI
  2. Confirmed transformant colonies inoculated to liquid LB with ampicillin
