Proteins are labeled by contacting the protein with a thiophosphorodichloridate reagent under conditions to effect chemoselective histidine conjugation. This technology provides numerous applications, including probing and enhancing protein function using histidine-directed chemistry. For example, our bioconjugation strategy can be used to generate bioconjugates on polyhistidine tags commonly found in recombinant proteins, as well as on single histidine residues. These bioconjugates, such as antibody-drug conjugates, immobilized antibodies or enzymes, PEGylated proteins and so on, can be used in pharmaceutics and diagnostics.
