Human erythrocyte glutathione S-transferase: a possible marker of chemical exposure

We have explored the possibility of using glutathione S-transferase (GST) as a biological marker of chemical exposure. All the model compounds tested in the present study (acrolein, propylene oxide, styrene oxide, ethylene dibromide and ethylene dichloride) showed a dose-dependent inactivation of erythrocyte GST in situ as well as the inhibition of purified erythrocyte GST.
