MHC-Peptide Tetramers: Powerful Tools for T Cell Research

MHC-peptide tetramers consist of four MHC molecules each loaded with a specific peptide antigen, conjugated to fluorochromes like BV421, PE, or APC for detecting antigen-specific T cells. Developed in 1996 by Stanford University School of Medicine researchers, these tools revolutionized T cell analysis via flow cytometry. They enable precise identification, quantification, and monitoring of T cell responses in immunology, vaccines, cancer, and more.
