General description

Monochlorobimane is a glutathione (GSH) fluorescent cell-permeable probe. When incubated with the test cell culture, it readily enters the cells and forms a fluorescent complex. The Monochlorobimane-GSH reaction is catalyzed by glutathione-S-transferase, which is detected fluorometrically.

Monochlorobimane, also known as mBCl, is a non-fluorescent compound that forms a fluorescent complex upon reaction. The fluorescence is detected at 394/490nm.

Application

Monochlorobimane is used as a fluorescent agent in fluorometric glutathione assays. It is used to detect the principal intracellular low-molecular-weight thiols, which play a pivotal role in the defense mechanism.
