Increased ATPase acid stability in type 1 fibers of rat soleus.
Type 1 fibers in skeletal muscle have been considered homogeneous on the basis of their acid-resistant ATPase activity. We have found that the Type 1 fibers in rat soleus are more resistant to prolonged acid pre-incubation than are those in other muscles.
