Recombinant Human Vascular Endothelial Growth Factor 121
VEGF 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. VEGF signals through 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. Due to its increased acidity, VEGF121 circulates more freely than other VEGF forms, which bind more tightly with vascular heparin sulfates. Recombinant Human VEGF121 is a 28.4 kDa, disulfide-linked homodimeric protein consisting of two 121 amino acid polypeptide chains.
Vascular Endothelial Growth Factor 121, VPF, VEGF-A
Yeast-derived Human VEGF121 protein,Ala27-Arg147(K115N).
Theoretically as a disulfide-linked homodimeric protein, the product consists of two 121 amino acid polypeptide chains. As a result of glycosylation, it migrates to at least two bands with molecular weights ranging from 14.4-20 kDa in SDS-PAGE under reducing conditions.

Sterile Filtered White lyophilized (freeze-dried) powder.
> 95% by SDS-PAGE and HPLC analyses.
Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using human umbilical vein endothelial cells (HUVEC) is between 0.2-0.4 ng/mL.
< 0.1 EU per 1μg of the protein by the LAL method.
Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH 7.4.
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.
Shipping and Storage
The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
1. Avoid repeated freeze-thaw cycle
