Recombinant Biotinylated Human HLA-A*11:01&B2M&KRAS WT (VVVGAGGVGK) Monomer Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Gly25-Thr305(HLA-A*11:01),Ile21-Met119(B2M) and VVVGAGGVGK peptide. Kirsten rat sarcoma 2 viral oncogene homolog (KRAS) is the most commonly mutated oncogene in human cancer. The developments of many cancers depend on sustained expression and signaling of KRAS, which makes KRAS a high-priority therapeutic target.
