Electroporation of cells:
- Add 1-2 l plasmid DNA (in water) to a minimum of 40 l
of electrocompetent cells. Homogenize by gently mixing
with pipette several times. Transfer mixture into a prechilled cuvette.
- Wipe moisture from the cuvette and insert the cuvette into the device.
- Electroporation:
Mode
Prokaryotes O
Voltage (V)
2,500 V
Time constant (T)
5 ms
- Immediately transfer cell suspension into LBG medium at a 1:25 dilution,
incubate 1 hour at 30 C.
- Plate cells on selective plates; incubate for 4 days.
Expected Results:
Transformation efficiency up to 5 x 10
5 transformants/g
of DNA.
