A biochemical study of non-specific esterases from plant cells, employing the histochemical substrate, naphthol AS-D acetate.

Abstract

The reagents routinely employed in the histochemical detection of nonspecific esterases, namely naphthol AS-D acetate and Fast Red Violet LB salt, have been used to study these enzymes biochemically with spectrophotometric procedures. A range of parameters that affect the coupling of the hydrolyzed substrate and diazonium salt were examined and their relevance to future histochemical procedures is noted.
