VEGF121 Protein, Human (Biotinylated, HEK293, His-Avi)
VEGF121 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. VEGF121 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived VEGF121 protein, expressed by HEK293 , with C-Avi, C-His labeled tag. The total length of VEGF121 Protein, Human (Biotinylated, HEK293, His-Avi) is 121 a.a., with molecular weight of ~18 kDa & 22-25 kDa, respectively.
- Species: Human
- Source: HEK293
-
Storage: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.

Background
VEGF121 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.
