Dihydropyridine receptor alpha 1 (DHPRα1) localization

Cross-sections of the gastrocnemius (a-h) and soleus (i-p) muscles were stained with anti-DHPRα1 antibody. Asterisks indicate normal immunoreactivity (IR) in the cytoplasm and subsarcolemma of DHPRα1 (a-d, i-p). Arrows indicate muscle fiber with ectopic DHPRα1 IR (e-h). Scale bar = 50 μm. GAS, gastrocnemius muscle; SOL, soleus muscle; 3M, 3-month-old mice; 24M, 24-month-old mice.
