A substrate comprises a surface, and a plurality of moieties, on at least a portion of the surface. The moieties are moieties of formula:
Surf-L—Q—T,
where —T comprises a reactant ligand, and Surf- designates where the moiety attaches to the surface. The substrate can be made into a protein chip by the reaction of a reactant ligand and a fusion polypeptide, where the fusion polypeptide includes a capture polypeptide moiety which corresponds to the reactant ligand.
底物包括一个表面和多个基团,至少在表面的一部分上。这些基团的化学式为:Surf-L—Q—T,其中—T包括一个反应配体,Surf-指示基团附着到表面的位置。通过反应一个反应配体和融合多肽,底物可以制成蛋白芯片,其中融合多肽包括一个捕获多肽基团,该基团对应于反应配体。
