Cartoon of the light-directed immobilization of a His-tagged protein on a microarray using the autoinhibition method. An undecapeptide construct (green) is created with a nickel-tris-(nitrilotriacetic acid) multivalent head group (nickel-tris-NTA) at the N terminus and a His-tag at the C terminus. Included within the peptide sequence is the photocleavable amino acid 3-amino-3-(2-nitrophenyl)-propionic acid and a single Cys for attachment of the construct to a microarray (or other molecules, in further …
