The first normal oral mucosa epithelium in which γ-glutamyl transpeptidase activity has been detected

A portion of consistently γ-glutamyl transpeptidase-positive epithelium in the normal oral mucosa of rats is described. This is the first normal oral mucosa epithelium reported to express activity of the trans...
