Abstract:
1. A support for performing an assay, comprising: a substrate having a pre-blocked binding polymer the formula (I): directly or indirectly attached to the substrate, having a plurality of maleic anhydride reactive groups (m) and a plurality of inactive groups (n), where X is a divalent NH, O, or S; R is H, or a substituted or an unsubstituted, linear or branched, alkyl group, an oligo(ethylene oxide), an oligo(ethylene glycol), or a dialkyl amine; R′ is a residue of a first unsaturated monomer that has been copolymerized with maleic anhydride; the relative ratio (m:n) of the maleic anhydride reactive groups to the inactive groups in the attached binding polymer is from 0.5 to 10, and the pre-blocked binding polymer does not contain a photoreactive group.
