Induced proliferation of HUVEC cells for Human VEGF-121. Cell proliferation was measured to calculate the ED50, which is as expected less than 5 ng/ml.
Non-reducing (-) and reducing (+) conditions in a 4 - 20% Tris-Glycine gel stained with Coomassie Blue. 1 μg of protein was loaded in each lane. Human VEGF-121 has a predicted Mw of 28.3 kDa (each monomer is 14.1 kDa).

Vascular Endothelial Growth Factor A (VEGF-A) is produced by a wide variety of cell types, including tumor and vascular cells. VEGF-A is a mediator of vascular growth, vascular permeability, and plays a role in stimulating vasodilation via nitric oxide-dependent pathways. VEGF-A has several alternatively spliced isoforms, with one being VEGF-121. The VEGF-121 isoform is a secreted protein that acts on receptors VEGFR-1 and VEGFR-2 to modulate endothelial cell function.

Activity Assay

Human VEGF-121 (Animal-Free) is fully biologically active when compared to standard. The activity is determined by the proliferation of HUVEC cells and it is typically less than 5 ng/ml. This corresponds to an expected specific activity of 2 x 105 units/mg.
