Isolation and characterization of the surface membranes of fast and slow mammalian skeletal muscle.


Fast (extensor digitorum longus) and slow (soleus) rat skeletal muscles served as the source for isolation and biochemical comparison of two distinct surface membrane fractions with properties of the sarcolemma and transverse tubular system. Enriched sarcolemmal membrane from soleus demonstrated a lighter density after sucrose density centrifugation. Sialic… (More)
