AMP deaminase histoenzymology in hamster skeletal muscle.

A histochemical technique for AMP deaminase (E.C. 3.5.4.6) has been successfully applied in hamster skeletal muscle tissue. Indeed the hamster gastrocnemius fast-glycolytic fibers show the strongest staining for AMP deaminase while the slow-oxidative fibers present only a week staining for this histoenzymatic method. The staining appears to stain strongly the capillary endothelium as well as is clearly localized in all fiber types associated with the actomysin since the stain is observed at the level of the A-band.
