- Harvest the cells in the exponential growth phase and centrifuge
them (for 5-10 minutes, 200 x g, at room temperature).
- Resuspend the cells in RPMI 1640 / 0.5% FCS, determine the number
of cells and centrifuge them (for 5-10 minutes, 200 x g, at room temperature).
Remove supernatant.
Note: The overall incubation time in the Eppendorf Electroporation
Buffer must not exceed 30 minutes to guarantee a successful electroporation!
- Resuspend the cells in Isoosmolar Electroporation buffer. When doi
