V09_17_1 Preparative double digestion of flhDC, FliC and pSB1C3 followed by ligation
  • Experiment:
    In order to clone the flhDC and FliC into pSB1C3, all components were digested with EcoRI and PstI according to the protocol. The restriction products were subsequently separated on a gel in order to verify the digestions success and purify the desired fragments. After measuring the concentration of the purified fragments, an overnight ligation was initiated.

    - 18C_flhDC
    - 20I_flhdc
    - 20E_motA
