substituents in the aromatic ring that increase the basicity of the aromaticamine. The rate of up to 40 M(-1) s(-1) between an electron-rich aldehyde and 5-methoxy-ABAO (PMA), which was observed at pH 4.5, places this reaction among the fastest known bio-orthogonal reactions. Reaction between M13 phage-displayed library of peptides terminated with an aldehyde moiety and 1 mM biotin-ABAO derivative reaches completion
