Bioorthogonal cleavage and exchange of major histocompatibility complex ligands by employing azobenzene-containing peptides

Angew Chem Int Ed Engl. 2014 Dec 1;53(49):13390-4. doi: 10.1002/anie.201406295. Epub 2014 Oct 27.

Abstract

Bioorthogonal cleavable linkers are attractive building blocks for compounds that can be manipulated to study biological and cellular processes. Sodium dithionite sensitive azobenzene-containing (Abc) peptides were applied for the temporary stabilization of recombinant MHC complexes, which can then be employed to generate libraries of MHC tetramers after exchange with a novel epitope. This technology represents an important tool for high-throughput studies of disease-specific T cell responses.

Keywords: bioorthogonal chemistry; cleavable linkers; immunology; major histocompatibility complex; peptidomimetics.
