Patent ID: 8304238

Claim:
An immobilized preparation of a cell adhesion protein or peptide for cell culture, comprising: a hydrophobic cell culture substrate, a cell adhesion protein or peptide, a hydrophobic binding-adsorptive polymer to which the cell adhesion protein or peptide has been covalently bound, wherein the hydrophobic binding-adsorptive polymer to which the cell adhesion protein or peptide is covalently bound, is adsorbed to the hydrophobic cell culture substrate by hydrophobic binding and not by chemical bonding, and wherein the hydrophobic binding-adsorptive polymer is selected from a copolymer of maleic anhydride and styrene; a copolymer of maleic anhydride and butyl vinyl ether; and a copolymer of maleic anhydride and hexyl vinyl ether.
