Native myosin isozymes of rat muscles have been isolated by electrophoreses in non‐dissociating conditions. Their mobilities were measured, using taenia coli myosin as an internal standard and their relative concentrations were determined by computer planimetry of the electrophoretograms. Three isozymes were observed in extensor digitorum longus (EDL), two in soleus (SOL), four in neonatal muscles and four in muscles three days before birth. Regenerates of minced EDL or SOL muscles in adult animals had no native myosin the third day after surgery; they were similar to neonatal muscles 15 days after surgery and to adult muscles 60 days after surgery.
