Biological Activity

Description

GMP VEGF165 Protein, Human is a Vascular Endothelial Growth Factor A (VEGF-A) isoform. VEGF is a heparin-binding growth factor specific for vascular endothelial cells that is able to induce angiogenesis.

Background

Vascular Endothelial Growth Factor (VEGF) has multiple isoforms, created by alternative splicing or proteolytic cleavage, and characterized by different receptor-binding and matrix-binding properties. These isoforms are known to give rise to a spectrum of angiogenesis patterns marked by differences in branching, which has functional implications for tissues. VEGF-A is a key member of the VEGF family of cytokines, along with VEGF-B, -C, -D, and PlGF. VEGF-A mediates angiogenesis, the expansion of an existing vascular bed by sprouting of new blood vessels. The vegfa gene is translated into a number of splice isoforms, the most notable in humans being VEGF121, VEGF165, and VEGF189[1].

Verified Bioactivity

Measured by its ability to induce calcineurin- NFAT signaling in 293-VEGF Res cells. The ED50 for this effect is 1.22 ng/mL.
