VEGF-121, an abundant splicing isoform of vascular endothelial growth factor (VEGF), exists as a disulfide-linked homodimer. It induces proliferation and migration of vascular endothelial cells, and is essential for both physiological and pathological angiogenesis. Contrast to other isoforms, VEGF-121 has very little affinity for heparin-sulfate proteoglycans, without recruiting Neuropilin1-expressing monocytes (NEMs), conferring to VEGF-121 the ability to diffuse freely, and increase tumor growth rate in vivo.
Measured in a cell proliferation assay using HUVEC cells，the EC50 for this effect is less than 2ng/ml.
Immobilized VEGF-121, Human (Cat. No. UA040082) at 0.5μg/mL (100μL/well) can bind Bevacizumab (starter-bio, Cat. No. S0B0437) with EC50 of 1.20-1.54 ng/mL.
1μg (R: reducing condition, N: non-reducing condition).
Immobilized VEGF-121, Human (Cat. No. UA040082) at 2.0μg/mL (100μL/well) can bind VEGF-R2/KDR Fc Chimera, Human (Cat. No. UA010144) with EC50 of 8.25-11.55 ng/mL.
