Application

Empigen BB is a zwitterionic detergent compatible with anionic, non-ionic, cationic and other amphoteric surfactants.

Empigen BB is a useful detergent that has been used in the solubilization of membrane proteins and biochemical analysis of keratins. It not only helps to solubilize bigger amounts of protein but it also maintains antibody reactivity. It has been also used in the purification of leucine-rich repeat kinase 2 (LRRK2) in Escherichia coli during research in Parkinson′s disease. The use of Empigen in the preparation of viral antigens is being increasing due to its effectivity in giving greater antibody responses.
