Transformation of E.coli XL1-Blue with pKS2µHyg-PAL-4Cl-CHS

Investigator: Ingmar, Volker

Aim of the experiment: Plasmid amplification

Operation Sequence:

  • melting of 100 µl Ca-competent E.coli XL1-Blue cells
  • addition of 1 µl of the Plasmid pKS2µHyg-PAL-4Cl-CHS
  • incubation for 30 min on ice
  • heat shock for 5 min at 37 °C
  • transfer of cells to 1 ml LB-medium without antibiotics and incubate at 37°C and 180 rpm for 30 min
  • plate 100 µl on an Amp-LB-plate
  • sediment the leftover in a centrifuge (30 - 60 sec, 13 000 rpm) and resuspend the sediment in 100 µl LB-medium and plate it as well on an Amp-LB-plate
