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