Junctophilin 2 (JPH2) localization

Cross-sections of the gastrocnemius (a-h) and soleus (i-p) muscles were stained with anti-JPH2 antibody. Asterisks indicate normal immunoreactivity (IR) to JPH2 in the cytoplasm and subsarcolemma (a-d, i-p). Arrows indicate muscle fiber with ectopic JPH2 IR (e-h). Scale bar = 50 μm. GAS, gastrocnemius muscle; SOL, soleus muscle; 3M, 3-month-old mice; 24M, 24-month-old mice.
