| abstract |
The present invention provides arrays, methods of constructing arrays, and methods of use of such arrays. The arrays of the invention comprise a substrate with two or more discrete constructs or discrete sets of constructs associated on the surface of the substrate, optionally via a linker molecule. The constructs include an oligonucleotide comprising a region encoding a peptide of interest and an affinity tag and an untranslated region, a fusion peptide comprising both the peptide of interest and the affinity tag and a capture agent that forms a binding pair with the affinity tag. |
