Recombinant Antibody
Specificity
The antibody reacts with v-H-ras (within amino acids 120-138) and rodent c-H-ras p21′s but not v-K-ras or rodent c-K-ras p21′s. This antibody also recognizes human c-H-ras and c-K-ras p21′s, but not human c-N-ras.
Alternative Names
Ras; p21ras;
UniProt

Immunogen
The original antibody was generated by immunizing mice with a synthetic peptide corresponding to amino acids 5-16 (KLVVVGAVGVGK) of a mutated RAS gene encoding Val instead of Gly at position 12 coupled to the carrier protein bovine thyroglobulin (BTG) and to keyhole limpet hemocyanin (KLH).
Application Notes
This antibody was capable of binding G12V and G12C mutant peptides of human ras protein in competition ELISAs (PMID: 3094010). It was reported to cross react with peptides containing amino acids V, A, C, H, I, L, M, Y, T, N, Q at position 12 in an ELISA (PMID: 9440050). This antibody could detect mutant KRAS proteins from cell lysates of human tumor cell lines in a western blot, but did not react with normal KRAS or other KRAS mutants. Immunohistochemical studies showed that DWP-labeled transformed NIH cells and human carcinoma cells contained p21ras is with either Val or Cys at position 12 but not normal or other activated KRAS protein (PMID: 3094010).
