Histochemical method for the demonstration of the activity of phosphoglucomutase

Summary

A method for the demonstration of the activity of phosphoglucomutase in tissues is described. In the histochemical system the enzyme converts the substrate α-D-glucose-1-phosphate to α-D-glucose-6-phosphate. The resulting α-D-glucose-6-phosphate is oxidized by exogenous glucose-6-phosphate dehydrogenase to D-glucono-δ-lactone-6-phosphate, whereby the activity of endogenous NADPH-tetrazolium oxidoreductase reduces Nitro-BT to the slightly soluble diformazan. The problems involved in the histochemical demonstration of phosphoglucomutase are discussed.
