Multiporator Transfection Protocol Protocol No. 4308 915.023 11/1999 Cell line BALB/3T3, mouse, embryo Transfection with Plasmid pEGFP-N1 (in bidistilled H2O) Electroporation buffer Eppendorf Hypoosmolar Electroporation Buffer (PH) Culture medium DMEM / 10% FCS Cuvette Eppendorf, 2 mm gap width, 400 l Temperature RT (20-25 C) Reference Eppendorf AG Application Hotline D-22331 Hamburg

  1. Harvest the cells in the exponential growth phase and centrifuge them (for 5-10 minutes, 200 x g, at room temperature).
  2. Resuspend the cells in DMEM / 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!

  3. Resuspend the cells in Hypoosmolar Electroporation Buffer. When doing so, set the cell concentration to 1 x 106 cells/ml.
  4. Add and mix plasmid DNA (5-20 g /ml final concentration, in bidistilled H2O).
  5. Transfer 400 l cell suspension into electroporation cuvettes (2 mm gap width). The cell suspension must be free of air bubbles.
  6. Electroporation:

    Mode Eukaryotes Voltage (V) 720 V Time constant (T) 40 s No. of pulses (n) 1
  7. After the pulse, allow the cell suspension to stand in the cuvette for 5-10 minutes at room temperature.
  8. Carefully transfer the cell suspension from the cuvette to 3 ml DMEM / 10% FCS, and cultivate them in a 55 mm culture dish.
Detection methods for transfection:
The expression of the plasmid pEGFP-N1 can be detected clearly after 24-48 hours with the aid of FACS analysis or under a fluorescence microscope. Result: Survival rate: 125% Transfection rate: 28% based on the initial number of cells used for the experiment Results were measured 48 hours after transfection.
