Abstract: The invention relates to a method for screening the binding properties of constituent peptides of MHC molecules by providing in solution MHC molecules or their constituent peptides for a set of MHC molecules including a plurality of subsets of MHC molecules, wherein the MHC molecules of each subset differ from MHC molecules of at least one other subset in at least one of the putative MHC binding peptide, an MHC alpha chain and an MHC beta chain, and loading said MHC molecules with an MHC binding peptide by (i) refolding of the MHC alpha chain and beta chain peptides in presence of said MHC binding peptide or (ii) by peptide exchange or loading with an unlabelled MHC binding peptide in the absence of any labelled MHC binding peptide, (b) taking of at least one sample from each subset, and (c) determining loading efficiency for the sample of step (b).

Abstract: The present invention relates to a method of producing a set of MHC molecules, and more precisely to a method of producing a set of MHC molecules which differ in their peptide bound in the binding groove. The method allows for parallel and rapid synthesis of different MHC molecules at high yields for each molecule.
