要旨

Probes for affinity guided conjugation have shown great promise for the preparation of high-quality protein conjugates. However, such probes are often limited in their protein scope. Here, we demonstrate the synthesis and use of imidazole carbamate probes for affinity guided conjugation of an azide handle to a wide variety of metal binding proteins such as antibodies, enzymes, nanobodies and His6-tagged proteins. The azide handles were used to link dyes to the proteins for gel analysis and binding studies. In a comparative study we find that the probe containing three NTA groups show higher selectivity than the probe containing two. In a mixture of proteins, the probe shows preference for labelling His6-tagged proteins.

Organic & Biomolecular Chemistry (OBC) publishes original and high impact research and reviews in organic chemistry. We welcome research that shows new or significantly improved protocols or methodologies in total synthesis, synthetic methodology or physical and theoretical organic chemistry as well as research that shows a significant advance in the organic chemistry or molecular design aspects of chemical biology, catalysis, supramolecular and macromolecular chemistry, theoretical chemistry, mechanism-oriented physical organic chemistry, medicinal chemistry or natural products. Articles published in the journal should report new work which makes a highly-significant impact in the field. Routine and incremental work is generally not suitable for publication in the journal. More details about key areas of our scope are below. In all cases authors should include in their article clear rationale for why their research has been carried out.
