In the electric current treatment of biological material (I) by taking up (I) in buffer solution of ionic strength at least 100 mM and generating an electric field of strength at least 1 kV/cm for a predetermined period of at least 10 mu s by potential impulse(s) (PI's), the buffer volume is at most 50 mu l, the PI is interrupted at least once for a period of at least 100 mu s and the PI's are continued sufficiently often to reach the predetermined PI duration. |
