摘要：

Mouse monoclonal antibodies (MAb) have been generated against the anionic isozyme of human glutathione S-transferase (GST-pi). MAb AGST 1 can inhibit 50-70% of GST-pi enzymatic activity and reacts with a 3-dimensional epitope which includes a putative glutathione binding site on GST-pi. A sandwich enzyme-immunoassay established using MAb AGST 1 and a polyclonal antibody displayed a sensitivity of 0.5 ng/ml. Immunohistochemical analysis of human tissues demonstrated marked increases in GST-pi levels in cancers of the brain, cervix, endometrium, colon, rectum and testis and in fibro- and chondrosarcomas.
