The protocols we used


Transformation

(estimated time: 3 hours and 30 min + 12-16 hours overnight incubation)

Materials needed:

  • LB agar plates with proper antibiotic added incubated at 37°C
  • Thawed Invitrogen TOP10 cells (every tube contains approximately 60 µl of competent cells)
  • Resuspended DNA
  • SOC medium


  • Put 4-6 µl of DNA resuspension into TOP10 tube.
  • Incubate on ice for 30-45 min.
  • Heat shock: 42°C for 1 min.
  • Put transformed TOP10 tube on ice and then add 250 µl SOC medium.
  • Incubate 2 hours at 37°C, 220 rpm.
  • Centrifuge 10 min, 1200 rpm.
  • Remove 150 ul of bacteria-free supernatant.
  • Plate the remaining part of solution (resuspending the bacteria) on a proper agar plate.
  • Incubate overnight at 37°C.
