Four carboxylic azo dyes, with spectroscopic absorption peaks ranging from 400 to 500 nm, are presented as new markers for amino acid and peptide labelling at their N-terminus. Labelling can also be performed at side-chain residues as is exemplified with lysine and serine. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
