Protocol for purification and identification of MHC class I immunopeptidome from cancer cell lines.


ABSTRACT: Major histocompatibility complexes (MHC) play a critical role in immunity by presenting peptides on the cell surface for T cell recognition. Identification of these peptides can be valuable to develop vaccines or immunotherapeutic strategies for infectious diseases and cancers. Mass spectrometry is the only tool available for unbiased identification of the immunopeptidome. Here, we describe a protocol for purification and identification of MHC class I peptides, including in-house purification of anti-MHC-antibody from hybridoma cells and the LC-MS/MS analysis of MHC-I bound peptides.
