title: Introduction of deoxyribonucleoside triphosphates into intact cells by electroporation.
abstract: A simple method, employing high-voltage electric discharge (electroporation), was developed to introduce phosphorylated nucleosides into the cytoplasm of viable cells. HL-60 leukemia cells permeabilized by this technique remained viable and incorporated deoxyribonucleoside triphosphates into nuclear DNA. Furthermore, DNA synthesis was depressed for at least 24 h in HL-60 cells made permeable to 1-beta-D-arabinosylcytosine 5'-triphosphate by this methodology. Electroporation was found to be applicable to the permeabilization of a wide variety of cell lines in culture to nucleotides, suggesting that this methodology may be useful for the introduction into intact cells of a wide variety of molecules that are not normally transported effectively.
