The peptides loaded in pHLA tetramers include KRAS-G12wt-9, KRAS-G12V-9 and a subset of KRAS codon 12 and 13 mutant peptides (KRAS-G12C-9, KRAS-G12D-9, KRAS-G12A-9, KRAS-G12S-9, KRAS-G12R-9, or KRAS-G13D-9) frequently observed in tumor specimens (Supplementary Table S2). This evidence concerns the gene KRAS and neoplasm.
