Using the semiconductor synthesis technology of maskless photolithography on microprocessor-grade silicon wafers, Jordan Price and colleagues synthesized microarrays containing every possible overlapping peptide in a linear sequence covering the N terminus of human histone H2B, including post-translational modifications. They demonstrated use of the 'on silico' peptide microarrays for the high-resolution mapping (at the single amino acid level) of epitopes targeted by commercially available H2B-specific antibodies and also by autoantibodies in samples from individuals with systemic lupus erythematosus.
