Bifunctional adsorbents for hydrophobic displacement chromatography of proteins.


The separation of pancreatic trypsinogen and alpha-chymochypsinogen A by displacement chromatography was tested on a bifunctional adsorbent containing both butyl and carboxymethyl groups. Methacrylic triblock copolymer was synthesized and used as the displacer. Compared to the displacement results on commercial Butyl-Sepharose, it was found that both the… (More)
