VEGF human

General description
VEGF (vascular endothelial growth factor) signals through the three receptors; fms-like tyrosine kinase (flt-1), KDR gene product (the murine homolog of KDR is the flk-1 gene product) and the flt4 gene product.[1] Recombinant human VEGF is a 38.2kDa disulfide-linked homodimeric protein consisting of two 165 amino acid polypeptide chains.
Application
VEGF human has been used as a chemoattractant for HUVECs (human umbilical vein endothelial cells) migration assay.[2] Biochem/physiol Actions
VEGF (vascular endothelial growth factor) is a potent growth and angiogenic cytokine. It stimulates proliferation and survival of endothelial cells, and promotes angiogenesis and vascular permeability. Expressed in vascularized tissues, VEGF plays a prominent role in normal and pathological angiogenesis.[3] Substantial evidence implicates VEGF in the induction of tumor metastasis and intraocular neovascular syndromes.[4][5] Polymorphism in VEGF at C(-634)G is linked with diabetic retinopathy in type 2 diabetes.[6] Physical form
Lyophilized with no additives.
Preparation Note
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a stabilizer (example 5% Trehalose) and store in working aliquots at -20°C to -80°C.
