Buffer: 0.22 μm filtered protein solution is in 5 mM citric acid, 5 mM NaHPO4, 0.15 M NaCl, pH 4.0.

Handling Advice: Avoid repeated freeze/thaw cycles.

Storage: -20 °C

Storage Comment: Unopened vial can be stored between 2°C and 8°C for one month, at -20°C for six months, or at -70°C for one year.

Target Details

Target: VEGFA (Vascular Endothelial Growth Factor A (VEGFA))

Alternative Name: VEGF-164

Background: The VEGF family includes VEGF-A, VEGF-B, VEGF-C, VEGF-D, and placental growth factor (PlGF). VEGF-A is generated as multiple isoforms by alternative splicing. These isoforms are generically identified as VEGFxxx where xxx refers to the number of amino acids. Rat isoforms include VEGF-120, VEGF-164, and VEGF-188. The VEGF gene is highly conserved among human, dog, cow, mouse, rat, pig, and chicken. VEGF164 plays a critical role in new blood vessel formation in vivo. VEGF164 induces angiogenesis on different levels. It acts as mitogen especially on endothelial cells, raises the vessel permeability and dilatation by releasing NO, and has chemotactic impact on monocytes/macrophages which plays a crucial role in inducing inflammatory neovascularization. Angiogenic activities of VEGFs are mediated primarily through the two receptors VEGFR-1 and VEGFR-2. VEGFR-2 signaling is enhanced by interactions with co-receptors such as heparin/heparan sulfate and Neuropilin 1. VEGF induces osteoclast migration and activation. In addition, it supports the survival of mature osteoclasts. These processes play a key role in repairing and remodeling during bone development.

Molecular Weight: The 164 amino acid recombinant protein has a predicted molecular mass of approximately 19.2 kDa. The protein migrates approximately at 25 kDa in DTT-reducing conditions and at approximately 50 kDa in non-reducing conditions by SDS-PAGE. The predicted N-te
