Background Information

RAS (derived from 'RAt Sarcoma' virus) gene family includes KRAS, HRAS, and NRAS. These genes encode very similar 21 kDa proteins and are homologs of rodent sarcoma virus genes that have transforming abilities. KRAS has two isoforms, 2A and 2B. This antibody is specific for KRAS-2A, which also named as KRAS-4A .
