Abstract:
1. A method for producing a protein-adsorbing material comprising activating a polymer base-material by exposing said polymer base-material to radiation with an irradiation dose of 1 to 20 kGy; bringing, with said polymer base-material activated, a vinyl monomer having a functional group having protein adsorption ability or a vinyl monomer having a functional group, to which a functional group having protein adsorption ability can be introduced, into contact, in a solution of the vinyl monomer, at 20° C. or less and for a period of 100 to 150 hours, thereby immobilizing a polymer side-chain formed by polymerization of said vinyl monomer to the surface of said polymer base-material and introducing a functional group having protein adsorption ability into said functional group, to which the functional group having protein adsorption ability can be introduced, and which is present in said vinyl monomer, when said vinyl monomer does not have said functional group having protein adsorption ability, wherein the mass of said polymer side-chain is 5 to 30% relative to the mass of said polymer base-material.
