This paper deals with the purification and the partial char-acterization of glutathione S-transferase (GST) isoforms from the clam Ruditapes decussatus. For the first step of purification, two affinity columns, reduced glutathione (GSH)–agarose and S-hexyl GSH–agarose, were mounted in series. Four affinity fractionswere thus recovered. Further purification was performed using anion exchange chroma-tography. Seven fractions,whichpresent aGSTactivitywith 1-chloro-2,4-dinitrobenzene (CDNB) as substrate, were collected and analyzed by RP-HPLC....
