Cloning of the mgtc promoter into the pSB1A3 plasmid

Kamil


Tasks:

  • Amplification of the mgtc promoter using new primers
  • pSB1A3 plasmid digest

Methods:

  • The PCR mix was prepared as follows:

    5μl buffer B (EURx)
    2μl 5mM dNTPs (EURx)
    5μl forward starter
    5μl reverse starter
    2μl OptiTaq polymerase (EURx)
    2μl Salmonella matrix
    29 μl H2O
  • PCR programme:

     4min 95°C 
    (30s 95°C, 35s 48°C, 40s 72°C)x28
    (30s 95°C, 35s 58°C, 40s 72°C)x28
    10min 72°C
    ~ 4°C
  • The PCR results were visualised with gel electrophoresis on 1% agarose gel.
  • The digest mix was prepared as follows:

    60μl plasmid isolation
    7μl Buffer O (Fermentas)
    1μl EcoRI enzyme
    1μl PstI enzyme
    1μl H2O
  • The digest was carried out in 37°C for 3h and inactivated for 15 min. in 80°C.
  • 1μl of CIAP enzyme was added after the inactivation and allowed to work for 1h in 37°C and was later inactivated for 15 min. in 85°C.
  • The resulting mix was separated on 1% agarose gel alongside the PCR and then selected bands were extracted for purification.

Results:

  • No gel picture, but the PCR worked so great that I decided not to irradiate the gel with UV light more than it was necessary for band extraction.

Conclusions:

  • The temperatures were chosen... wisely.
