Transcutaneous in vivo electroporation for skeletal muscle. After the injection of 25 μg of plasmid into the gastrocnemius muscle, transcutaneous in vivo electroporation was performed via the skin of the calf to drive the gene transfer. The conditions were 8 pulses of 100 V, 50 msec. *, plasmid-injected area; arrows, electrodes.
