Description
VEGF165, the predominant pro-angiogenic isoform in human physiology, drives endothelial cell proliferation and vascular permeability through high-affinity receptor engagement, making quantitative assessment of its binding kinetics essential for angiogenesis research and antibody development. This mammalian-expressed protein spanning residues 27–191 demonstrates robust receptor interaction, binding immobilized FLT1 (VEGFR-1) with an EC50 of 28.72–33.22 ng/mL in functional ELISA, a result that supports its use in receptor-ligand competition assays, surface plasmon resonance studies, and cell-based angiogenesis models including endothelial tube formation and wound healing experiments. The same preparation binds an anti-VEGFA monoclonal antibody with an EC50 of 0.68–0.84 ng/mL, providing a quantitative benchmark for antibody characterization, neutralization assays, and ELISA standard curve generation. Purity exceeding 95% by SDS-PAGE and endotoxin below 1.0 EU/μg align with standards expected in cell proliferation assays and in vivo tumor vascularization models where low contaminant levels are critical.
