Effect of varying the preincubation and incubation temperature on the reaction pattern for myosin ATPase in rat skeletal muscle.
The temperature of the preincubation and incubation medium influences the staining pattern and intensity of the reverse myofibrillar ATPase in rat skeletal muscle. The activity in some fibers was raised and in others depressed by varying the temperature of the preincubation and incubation medium between 4 and 37 degrees C. This indicates the presence of reverse ATPase isoenzymes with different temperature sensitivities.
