To characterize the reactivity of EMab-17 to CRC cell lines, we used CRC cells with KRAS p.G13D (HCT-15, HCT-116, DLD-1), KRAS p.G12V (HCT-8), KRAS p.G12A (SW1116), KRAS p.G12D (LS174T) and KRAS wild-type (Caco-2, HT-29, COLO201, COLO205). The gene discussed is KRAS; the disease is colorectal carcinoma.
