Abstract

A method involving direct affinity chromatography of undialysed bovine seminal plasma on a calmodulin-agarose column was developed for the purification of seminalplasmin. Seminalplasmin thus obtained was further purified from any contaminants left by ion-exchange chromatography on a short CM-Sepharose column. The method gave an excellent yield of seminalplasmin (0.7 mg per ml seminal plasma) that showed 100% inhibition of bacterial growth at a concentration of 10 micrograms/ml. The purified seminalplasmin was found to be homogeneous as tested by HPLC on a reverse-phase column and SDS-PAGE.
