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.

Enhanced monoterpene emission in transgenic orange mint (Mentha × piperita f. citrata) overexpressing a tobacco lipid transfer protein (NtLTP1).

Hwan-Su Hwang et al.

Planta, 252(3), 44-44 (2020-09-03)

Overexpression of the tobacco lipid transfer protein (NtLTP1) gene in transgenic orange mint resulted in enhanced accumulation of monoterpenes in the cavity of head cells of glandular trichomes, which resulted in enhanced emission of monoterpenes from transgenic orange mints. Plants
