Effect of EA pretreatment on Cx
protein content in heart of rats subjected to SGIR. Panel A: Representative traces of electrophoresis of myocardial Cx43 protein at 41 and 46 kilo-Dalton after probed with polyclonal anti-Cx43 antibody in different groups. Panel B: Group results showing the changes of relative density of myocardial Cx43 protein in different groups. Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) was taken as the internal control. (n = 20).
