A method for the one-step purification of high-complexity peptide microarrays is presented. The entire peptide library is transferred from the synthesis support to a gold coated polyvinylidenfluoride (PVDF) membrane, whereby only full-length peptides covalently couple to the receptor membrane via an N-terminally added cysteine. Highly resolved peptide transfer and purification of up to 10 000 features per cm2 is demonstrated.

Special delivery: The “freezing” of activated amino acid derivatives within solid particles enables a laser printer to deliver these “postal packages” to defined locations on a solid support with high resolution. Subsequent parallel coupling is initiated simply by melting a whole layer of 20 different amino acid particles (see schematic representation; Fmoc=9-fluorenylmethoxycarbonyl).
