HISTOCHEMICAL DEMONSTRATION OF A TRYPSIN-LIKE ESTERASE ACTIVITY IN MAST CELLS

Abstract
Histochemical localization of an enzymic activity hydrolyzing naphthol AS epsilonaminocaproate esters in human and canine tissues and having activity characteristics similar to that of a trypsin-like mast cell enzyme hydrolyzing benzoyl-DL-arginine-B-naphthylamide is described.
