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.

Components

This product contains 0.48 mM 4-chloro-1-naphthol, 50 mM Tris-HCl, 0.2 M NaCl and 17% methanol.

Other Notes

0.48 mM 4-chloro-1-naphthol, 50 mM Tris-HCl, 0.2 M NaCl and 17% methanol.

Principle

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