Description: Stability and Storage:The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 10% prior to the expiration date under appropriate storage condition. Detection method:Colorimetric Sample type:Plasma, Serum Assay type:Quantitative Sensitivity:0.156 μg/ml Range:0.31-5 μg/mL Recovery:80-120% Background:Ramucirumab is a human monoclonal antibody (IgG1) against vascular endothelial growth factor receptor 2 (VEGFR2), a type II transmembrane tyrosine kinase receptor expressed on endothelial cells. By binding to VEGFR2, Ramucirumab prevents binding of its ligands (VEGF-A, VEGF-C, and VEGF-D), thereby preventing VEGF-stimulated receptor phosphorylation and downstream ligand-induced proliferation, permeability, and migration of human endothelial cells. Shipping:2-8 ℃ Specifications:Ramucirumab Note:For Research Use Only.
