See also transfection. electroporation (i·lekˈ·trō·p n technique by which cell membranes are made permeable by rapid pulses of high-voltage current. Has been used to treat cancers. electroporation the use of high-voltage electrical impulse to create pores through a cell membrane and allow uptake of DNA into a cell.

Huang and his Pittsburgh colleague Feng Liu recently modified the electroporation process so that a metal syringe can double as the electrode. Intramuscular delivery of DNA vaccines using Inovio's proprietary electroporation technology has been shown in primate studies to boost the immune response by orders of magnitude over DNA plasmid alone. By redesigning the environment in which electroporation occurs, he's been able to drop the current to one-thousandth of what had previously been needed. |
