Substrate surface is suppressed nonspecific adsorption

摘要

Being the backing material surface where the substance or suffering analysis ones in order to detect suffering analysis ones is locked, on the backing material surface simultaneously with the said substance or suffering analysis ones, or after the said substance or suffering analysis ones is locked on the said surface, processing in the non building a bridge polymer content liquid which designates the polyethylene glycol chain and-segment as the base, the backing material surface which was formed is offered. Coexists in the sample which was measured non unique adsorption of the careless protein and the like is controlled significantly.
