title: Generation of peptide MHC class I monomers and multimers through ligand exchange.
abstract: The recognition of defined antigen-MHC complexes by antigen-specific T cells forms the molecular basis of T cell immunity. It has been shown that fluorescently labeled recombinant MHC tetramers can be utilized to detect antigen-specific T cells by flow cytometry. Since this first description, MHC tetramers and other types of MHC multimers have become a core tool to monitor the development of disease- and therapy-induced antigen-specific T cell responses both in humans and in animal model systems. This unit describes a set of protocols that transform classical MHC multimer technology into a high-throughput platform, allowing one to produce large collections of MHC class I molecules charged with different peptides. This technology is based on the development of conditional MHC ligands that can be triggered to self-destruct while in the MHC-bound state.
