Cav2, Cav1, and Cav3 protein expression in gluteus maximus muscle (GM) of wild-type (WT) and Cav2−/− mice. A: immunoblots for Cav2, Cav1, Cav3, and GAPDH extracted from whole muscle lysates. B–D: summary data for quantitative densitometric ratios of Cav2/GAPDH, Cav1/GAPDH, and Cav3/GAPDH immunoblots are calculated as means ± SD; n = 3 per group.
