摘要

Apparatus for electrophoretic transfer of nucleic acids, peptides, proteins and/or other biologically active molecules into eukaryotic cells comprises two capacitors, each connected to a high voltage source. Apparatus for electrophoretic transfer of nucleic acids, peptides, proteins and/or other biologically active molecules into eukaryotic cells comprises two capacitors (7, 8), each connected to a high voltage source (5, 6). Each capacitor discharges via a power transistor (9, 10) into a cuvette holding the cell sample. The first capacitor is charged with a preset voltage U1 and the second with a voltage U2 given by the equation: U2 = R x I2 x K2, R1 = the resistance of the cuvette and suspension in it I2 = the desired current K2 = a correction factor based on the properties of thee cuvette
