Article Abstract

A new type of flaky affinity resin for capture of the target proteins was prepared to discuss its properties compared with those of a particulate affinity resin. The resin prepared had totally co-continuous structure (monolith) and was utilized in the shape of flake. The concentration of surface amino groups for immobilization of ligand was determined to be 22.3 micromol/ml. Immobilizations of ligand such as Sulfonamide, Ketoprofen, Captopril, or Methotrexate (MTX) on the affinity resin were quantitatively proceeded to afford fully covered (100%) affinity resins. Control of the immobilization rate of affinity resin using Sulfonamide or Ketoprofen was successfully achieved with the calculated immobilization rate. The flaked shape of affinity resin (100-400 microm) presumably simplified affinity experimental procedures and the affinity resin immobilizing Sulfonamide effectively captured one of the target proteins, CAII, without non-specifically bound proteins. The observed properties of the flaky affinity resin as well as ease in handling are really useful for capture of the target proteins of possible rare ligands.
