These fractions are tested for recognition by T cells and compared to the recognition of a synthetic ligand that is presumed to be the recognized epitope. Identical HPLC fractionation and T cell recognition patterns confirm that the specific ligand was presented by MHC molecules. coelution assay measuring MHC ligand processing and presentation using T cell recognition of HPLC fractionated eluate compared to synthetic ligand ligand presentation|coelution PERSON:Randi Vita, Jason Greenbaum, Bjoern Peters detection technique assay measuring binding of a T cell epitope:MHC:TCR complex assay measuring MHC ligand processing and presentation metadata complete
