[Investigation of glutathione-S-transferase isozymes in human lenses].

Glutathione-S-Transferase (GST) isozymes in human lenses were investigated by the immunoenzymatic method using antibody against human liver GST2 and GST3 after polyacrylamide gel isoelectric focusing (western blotting method). Also, rocket immunoelectrophoresis was carried out for the detection of GST1. It was found that GST1 in lens also showed a polymorphism. The GST2 was not found in human clear lenses as well cataractous lenses. In addition, crossreacting materials against both antisera of GST2 and 3 were detected in the pH 6-7 area of the gel in all human lenses.
