The use of HPLC-MS in T-cell epitope identification.
The hunt for T-cell epitopes is going on because hopes are set on such peptide sequences for diagnosis and vaccine development in the fight against infectious and tumor diseases. In addition to a variety of other techniques used in T-cell epitope identification, mass spectrometers coupled to microcapillary liquid chromatography have now become an important and sensitive tool in separation, detection, and sequence analysis of highly complex natural major histocompatibility complex (MHC) ligand mixtures. In this article, we review the basics of mass spectrometric techniques and their on-line coupling to microcapillary liquid chromatography (microcap-LC). Furthermore, we introduce current strategies for the identification of new T-cell epitopes using microcapillary liquid chromatography-mass spectrometry (microcap-LC-MS).
