Peptide microarrays for determination of cross-reactivity.
Polyclonal antibodies raised against full-length antigens are often used for localization experiments. Exact knowledge of epitopes in the antigen recognized by the antiserum is important if the target antigen belongs to a large family of proteins which are highly conserved. We have shown that epitope mapping using peptide microarrays represents a powerful tool for determination of immunodominat regions in a proteome-wide manner. As examples we show results of epitope mapping using peptide microarrays displaying overlapping peptide scans through either all human cyclophilins or all human FK506-binding proteins.
