title: Synthesis and characterization of a biospecific adsorbent containing bovine serum albumin as a ligand and its use for bilirubin retention.
abstract: Epoxy-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 mg/g dry gel) were obtained. Bilirubin retention of 3.10 mg/g of these beads was observed at 5 degrees C.
