General description

4-Chloro-1-naphthol is a substrate for HRP in a reaction that results in a colored precipitate. It is commonly used for colorimetric detection and visualization of proteins in western blotting.

Application

Suitable for visualizing protein-peroxidase conjugates in western blotting.

Biochem/physiol Actions

Enzymes such as HRP convert 4-Chloro-1-naphthol to a purple-colored precipitate on the blot that is readily visible to the eye.
