Circular dichroism determination of class I MHC-peptide equilibrium dissociation constants
Abstract
Class I major histocompatibility complex (MHC) molecules bind peptides derived from degraded proteins for display to T cells of the immune system. Peptides bind to MHC proteins with varying affinities, depending upon their sequence and length. We demonstrate that the thermal stability of the MHC-peptide complex depends directly on peptide binding affinity. We use this correlation to develop a convenient method to determine peptide dissociation constants by measuring MHC-peptide complex stability using thermal denaturation profiles monitored by circular dichroism.
