REFINEMENT OF THE BIS-(THIOACETOXY) AURATE (I) METHOD FOR THE ELECTRON MICROSCOPIC LOCALIZATION OF ACETYLCHOLINESTERASE AND NONSPECIFIC CHOLINESTERASE

Abstract

The bis-(thioacetoxy) aurate (I) histochemical method has been refined to permit reliable electron microscopic localization of acetylcholinesterase and nonspecific cholinesterase in autonomic ganglia and other mammalian and submammalian tissues. The detailed procedure is presented, along with illustrations of its specificity by light microscopy and high degree of resolution by electron microscopy.
