Revision as of 12:54, 12 January 2015

Materials:

  • Ice
  • 4 mM cuvettes, N+1 cuvettes
  • Steinberg's, at 4 C.
  • Square pulse electroporator (we use the BTX 830 Squarporator)

    Procedure:

    1. Put cuvettes on ice, and cool down Steinberg's on ice
    2. Trypsinize cells as normal, stop reaction with high serum media and spin down at 1000 rpm, 3 minutes
    3. Wash pellet with Steinberg's solution and resuspend in 300 µl of Steinberg's, keep on ice
    4. Before electroporation, make sure to electroporate a cuvette with no cells to discharge device
    5. Electroporate cells in following conditions and put back on ice: Myoblasts: 100V, 35 msec, 5 pulses, Myotubes: 75 V, 35 msec, 5pulses
    6. Plate cells as normal
