Biological Activity Comment
Immobilized Human KRAS G12V (HLA-A*03:01) Tetramer, His Tag at 5μg/ml (100μl/Well) on the plate. Dose response curve for Anti-KRAS G12V (HLA-A*03:01) Antibody, hFc Tag with the EC50 of 0.58μg/ml determined by ELISA (QC Test). The affinity constant of 42.3 nM as determined in SPR assay (Biacore T200). See testing image for detail.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/mL is recommended. Dissolve the lyophilized protein in distilled water.
缓冲液
Lyophilized from 0.22μm filtered solution in PBS ( pH 7.4). Normally 8 % trehalose is added as protectant before lyophilization.

背景
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. The virtual screening approach to discover novel KRAS inhibitors and synthetic lethality interactors of KRAS are discussed in detail.
分子量
258 kDa. Due to glycosylation, the protein migrates to 260-265 kDa under Non reducing (N) condition based on Tris-Bis PAGE result.
