Penile eNOS protein in wild-type and nNOS − mice
eNOS protein levels were derived from intensities of protein bands localized by Western blot analysis of penile homogenate supernatants, standardized for each experiment by serial dilutions of human endothelial lysate. The data are expressed as means (thick horizontal lines) ° SEM (thin horizontal lines) for seven experiments. The amount of eNOS protein is significantly less in the wild-type group than in the nNOS− group (p < 0.05).
