A main object of the invention is to provide a polymer compound for medicine which has an excellent capability of fixing a biologically active substance and has such chemical/physical stability that the compound is less dissolved or deteriorated in a washing step, in particular, which can be suitably applied to a plastic substrate surface. The invention provides a polymer compound for medical material which is a polymer comprising repeating units derived from an ethylenically unsaturated polymerizable monomer (a) having a functional group for fixing a biologically active substance, wherein the polymer has a reactive functional group on at least one terminal side thereof, and a biochip substrate wherein a layer containing the polymer compound is formed on a substrate surface, thereby attaining the object.

Polymer compound for medical material, and biochip substrate using the polymer compound

A biochip substrate capable of realizing the high detection accuracy by restricting a nonspecific adsorption or bonding of a substance to be detected, when used for a detection or analysis of protein, nucleic acids and the like. The biochip substrate is for fixing a biologically active substance on a surface of a solid substrate, and characterized in that it has a layer comprising a polymer compound obtained by copolymerizing an ethylenically unsaturated polymerizable monomer having an alkylene glycol residue, an ethylenically unsaturated polymerizable monomer having a functional group for fixing a biologically active substance and an ethylenically unsaturated polymerizable monomer having a cross-linkable functional group, on the surface of the substrate.
