Recent Advances in Controlled Immobilization of Proteins onto the Surface of the Solid Substrate and Its Possible Application to Proteomics

Proteome analysis plays a key role in the elucidation of the functions and applications for numerous proteins. For proteome analyses, various microplate- and microarray-based techniques have been developed by a number of re- searchers. Their intent was to immobilize proteins on the surface of a solid substrate in a site-directed manner while re- taining structure and native biological function. In this review, we focus on recent advances in immobilization methodol- ogy for proteins/enzymes on a surface, including those using the affinity peptides screened by random peptide library sys- tems. We also discuss applications of the affinity peptide-mediated immobilization method in fields related to proteome analysis, particularly our recent work concerning immunoassay and protein-protein interaction analysis.
