Table 1 Comparison of the different injection and electroporation techniques. Intramuscularly injected mice are represented as IM and intra-arterially injected mice are represented as IA. Mice that were electroporated are identified with a + sign and mice that were not electroporated are identified with a - sign. The four different electrode types are identified with letters that correspond to the letters in figure 3. ^a mean % β-Gal expression = average value of [β-Gal activity (mg)/total protein (mg)]. ^b,c,d,e,f,g statistical significance (p < .05) between groups with differing superscripts. n = 7 for each treatment group.
