The graft copolymers Nylon-co-hydroxyethylmethacrylate and poly(ethylene)-co-hydroxyethylmethacrylate coupled to Cibacron blue F3GA at wet volume levels similar to those obtained with Sepharose 4B. However, the graft copolymers removed protein from human serum to a far lesser extent than did Sepharose 4B. Further investigations involved the preparation of hydrolyzed poly(vinyl acetate) copolymers of nylon and polyethylene and of cellulose-co-hydroxyethylmethacrylate and study of the ability of the copolymers to remove human serum albumin and lactic dehydrogenase. Comparisons were made with Sepharose 4B-, Sephadex G15-, and G25-based Cibacron blue F3GA systems. The effectiveness of Sepharose 4B-Cibacron blue F3GA is thought to be due to the manner in which the dye is located within the pores of the gel.
