poxy-activated gels from cross-linked polybutadiene-hydroxyethylmethacrylate -PB-HEMA. copolymer and epichlorohydrin -ECH. were prepared and characterized. Albumin was covalently bonded to the matrix and used as support of affinity chromatography in bilirubin -BR. retention experiments. PB-HEMA-ECH with different amounts of immobilized albumin between 5.20 and 6.80 mgrg dry gel. were obtained. Bilirubin retention of 3.10 mgrg of these beads was observed at 5 8C.
