Abstract
The present disclosure provides a method of identifying a peptide antigen, including contacting an antibody-comprising composition to a peptide microarray having an array surface and a plurality of feature pairs disposed thereon. Each of the feature pairs includes a first feature of wild-type peptides having a defined sequence and a second feature of mutant peptides having the defined sequence with a single amino acid mutation. Each of the wild-type peptides and the mutant peptides has an array-coupled terminus coupled to the array surface and an opposing free terminus, and the position of the amino acid mutation in the mutant peptides is located closer to the array-coupled terminus of the mutant peptides than the free terminus. The method further includes detecting binding of an antibody in the antibody-comprising composition to at least one of the feature pairs on the peptide microarray, and identifying feature pairs exhibiting differential binding.
