Differential expression of RyR1 and RyR3 in D25 diaphragm muscle. Longitudinal and cross-sections of D25 mouse diaphragm muscle were immunolabeled with antibodies against RyR1 (a and c) and RyR3 (b and d). Anti-RyR1 stains all muscle fibers, but anti-RyR3 stains only a fraction of the muscle fibers at this developmental stage. Serial sections (c and d) show that the fiber that expresses RyR3 (d) also contains RyR1 (c). Bar, 10 mm.
