We tried to identify the KRAS5−6/8−14 G12V spliced and the KRAS5−14 G12V non-spliced epitope candidates through the MS measurement of the HLA-I immunopeptidomes of the SW480 pancreatic adenocarcinoma cell line, which expresses the HLA-A*02:01 complex and the KRAS G12V mutated protein (42). Here, KRAS is linked to pancreatic adenocarcinoma.
