An electron microscopic histochemical investigation of the localization of creatine phosphokinase in heart cells.
The results of an electron microscopic histochemical investigation performed in the current study indicate that in heart cells creatine phosphokinase is localized: (1) inside mitochondria mainly on the cristae membranes, (2) on the membrane of the sarcoplasmic reticulum, (3) on myofibrils (and in cytoplasm), (4) on the plasma membrane of the cells, (5) on the membrane of the cell nuclei.
