Peptide binding to empty HLA-B27 molecules of viable human cells.

Abstract excerpt

Intracellular binding of antigenic peptides by polymorphic class I major histocompatibility complex molecules creates the ligands recognized by receptors of CD8+ T cells. Previously described in vitro assays of peptide binding to class I molecules have been limited by either the low proportion of accessible binding sites or the lack of allelic specificity. Here we describe a system in which the human class I...
