Anti-Human VEGF

Purified Recombinant Human VEGF (>98%)

This antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 containing 5.0% w/v trehalose with no calcium, magnesium, or preservatives present.

Lyophilized

The lyophilized antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for twelve months from date of receipt. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.

Immunohistochemistry: Suitable for use at concentration of 3-15 µg/mL.
Immunocytochemistry: Suitable for use at concentration of 5-15 µg/mL.
Neutralization: Measured by its ability to neutralize VEGF165-induced proliferation in HUVEC human umbilical vein endothelial cells. Conn, G. et al. (1990) Proc. Natl. Acad. Sci. USA 87:1323. The Neutralization Dose (ND₅₀) is typically 0.02‑0.12 µg/mL in the presence of 10 ng/mL Recombinant Human VEGF165.

Goat Anti-Human Vascular Endothelial Growth Factor (VEGF) recognizes Human VEGF. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.

Vascular endothelial growth factor (VEGF), a potent proangiogenic cytokine¹ is the key signal used by oxygen-hungry cells to promote growth of blood vessels. It binds to specialized receptors on the surfaces of endothelial cells and directs them to build new vessels.² VEGF are crucial regulators of vascular development during embryogenesis (vasculogenesis) and blood-vessel formation in the adult (angiogenesis). Abnormal VEGF function is associated with inflammatory diseases including atherosclerosis, and hyperthyroidism.^3,4,5,6
