VEGF183 Protein, Human (sf9)

VEGF183 Protein is a subtype of Vascular Endothelial Growth Factor A (VEGF-A). VEGF-A is a key member of the VEGF family of cytokines that can promote neovascularization and increase vascular permeability. VEGF183 Protein, Human (sf9) is the recombinant human-derived VEGF183 protein, expressed by Sf9 insect cells , with tag free. The total length of VEGF183 Protein, Human (sf9) is 183 a.a., with molecular weight of ~21 KDa.

VEGF183 is a subtype of Vascular Endothelial Growth Factor A (VEGF-A). VEGF-A is a growth factor active in angiogenesis, vasculogenesis, and endothelial cell growth. VEGF-A induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis, and induces permeabilization of blood vessels. VEGF-A binds to the FLT1/VEGFR1 and KDR/VEGFR2 receptors, as well as heparan sulfate and heparin. It also binds to the NRP1/neuropilin-1 receptor. When VEGF-A binds to NRP1, it initiates a signaling pathway needed for motor neuron axon guidance and cell body migration, including the caudal migration of facial motor neurons from rhombomere 4 to rhombomere 6 during embryonic development. Additionally, VEGF-A binds to the DEAR/FBXW7-AS1 receptor.

Approximately 21 kDa.

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of pH 7.92 100 mM glycine , 10 mM NaCl. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
