Abstract: The sulfhydryl groups of the reduced glutathione (GSH) have been reacted with 2,4-dinitrochlorobenzene to give S-protective glutathione as a hapten, The haptens were crosslinked with the amino groups on the surface of BSA (Bovine Serum Albumin) glutaraldehyde,The covalent conjugates are GSH specific antigens of high immunogenicity.The antigens were found to be homogenious and have a molecular weight of 87000 dalton as determined by gel-electrophoresis method.Spectral and circular dichroism measurements showed that the antigens possess special vis-UV spectra, fluorescence nature with a increased compact of antigen structure.

Key words: glutathione peroxidase, catalytic antibody, specific antigen, preparation
