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

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

Investigator: Ingmar, Volker

Aim of the experiment: Plasmid purification

Operation Sequence:

  • A single clone of E.coli XL1-Blue with pKS2µHyg-PAL-4Cl-CHS was picked an transferred to 5 ml LB Amp on saturday evening. Incubation overnight at 37°C 180 rpm.
  • Using a Quiagen kit a miniprep of the overnight culture was done.

Quick Change mutagenis to remove NgoMIV from pYES2

Investigator: Ingmar, Volker

Aim of the experiment: Removal of a NgoMIV restriction site in the backbone of pYes2.

Operational sequence:

  • A single clone of E. coli pYes2 1.2 was picked an transferred to 5 ml LB Amp. Incubation overnight at 37°C 180 rpm.
