Synthetic oligopeptides chemically modified with environmentally sensitive fluorophores enable real-time visualization of peptide binding to MHC molecules. This technology will expand our understanding of antigen presentation and enable visualization of fluorescent peptide binding to a wide variety of receptors in living cells.
