Description générale

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.

Decreases in GSH pools detected during ischemia sensitize neurons to excitotoxic damage. Thermodynamic analysis predicts that partial GSH depletion will cause an oxidative shift in the thiol redox potential. To investigate the acute bioenergetic consequences, neurons were exposed to monochlorobimane

Previously we reported the purification of soluble gamma-glutamyltransferases (GGTs) from radish cotyledon. Subcellular fractionation of radish cells revealed that soluble GGT is a vacuolar enzyme.
