Preparation of stable single-chain trimers engineered with peptide, beta2 microglobulin, and MHC heavy chain.
This unit describes a method for constructing a class I MHC molecule with a bound peptide as a single polypeptide chain, termed SCT, for single chain trimer. The component organization of the SCT appears to be widely applicable to different mouse or human MHC class I isotypes bound by different antigenic peptides. The enhanced peptide occupancy afforded by the SCT format makes these molecules effective reagents as DNA vaccines, multimeric staining reagents to enumerate CD8 T cells, and probes of lymphocyte biology.
