Materials
- Ice
- 4 mM cuvettes, N+1 cuvettes
- Steinberg's, at 4 C.
- Square pulse electroporator (we use the BTX 830 Squarporator)
Steinberg's
1x | FW (MW) | 5x/500 ml |
---|---|---|
58 mM NaCl | 58.44 | 8.47 g |
0.67 mM KCl | 74.56 | 1.68 ml (1M) |
0.44 mM Ca(NO3) | 236.20 | 1.1 ml (1M) |
1.3 mM MgSO4 | 246.47 | 3.25 ml (1M) |
4.6 mM | Tris pH 7.8-8.0 | 5.75 ml (2M) |
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
