Tests for development of the electroporation's protocol

  • Re-launch of 50mL of Pseudovribrio in MB and M9 from pre-culture of 4th August.
  • Incubation at 30°C and waiting for the exponential growth phase.
    > OD(600nm) in M9 = 0.15
    > OD(600nm) in MB = 1.5

    WORK IN ICE

  • Centrifuge 10min at 4000rmp and 4°C
  • Wash cells 1:2 of the initial volume with cold sorbitol, cold MiliQ H2O or cold glycerol 10%
  • Centrifuge 10min at 4000rmp and 4°C
  • Wash cells 1:10 of the initial volume with cold sorbitol, cold MiliQ H2O or cold glycerol 10%
  • Centrifuge 10min at 4000rmp and 4°C
  • Resuspend cells 1:100 of the initial volume with cold sorbitol, cold MiliQ H2O or cold glycerol 10%
