Naphthol AS-OL is a widely used chromogenic enzyme substrate that forms a colored product upon reaction with specific enzymes. It is commonly employed in histochemical and cytochemical staining techniques to visualize enzyme activity in cells and tissues. Naphthol AS-OL is particularly useful for detecting the presence of enzymes such as alkaline phosphatase, acid phosphatase, and esterases. The resulting colored product can be easily observed under a microscope, allowing researchers to study the distribution and localization of these enzymes in various biological samples.
