Cytochemical reaction
WebCytochemical evaluation was performed, including periodic acid-Schiff reaction, Sudan black B, alpha-naphthyl acetate, alpha-naphthyl butyrate, naphthol AS-D chloroacetate, and acid phosphatase stains. The results of these studies confirmed the morphologic impression and diagnosis of ALL. Ultrastructural evaluation revealed that the granules ... WebReaction between substrate and enzyme yields either an insoluble electron-dense reaction product, or a soluble electron-translucent one that requires a further ‘capture’ step to produce a final electron-dense precipitate visible in the TEM. ...
