||Recombinant full length mature Human VEGF 121B with His tag at N terminal produced in the endosperm tissue of barley grain ; 126 amino acids with tag, Predicted MWt 14.4 kDa.
||This gene is a member of the PDGF/VEGF growth factor family and encodes a protein that is often found as a disulfide linked homodimer. This protein is a glycosylated mitogen that specifically acts on endothelial cells and has various effects, including mediating increased vascular permeability, inducing angiogenesis, vasculogenesis and endothelial cell growth, promoting cell migration, and inhibiting apoptosis. Elevated levels of this protein is linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy. Alternatively spliced transcript variants, encoding either freely secreted or cell-associated isoforms, have been characterized. There is also evidence for the use of non-AUG (CUG) translation initiation sites upstream of, and in-frame with the first AUG, leading to additional isoforms.
||The ED50 is determined by Cell Proliferation Assay for the dose-dependent effects of serial dilutions of Human VEGF 121B on HUVEC cells. The ED50 lies typically in the range of 2.8-4.3 ng/ml.
||Lyophilised:Reconstitute the lyophilized protein in sterile phosphate-buffered saline to a concentration of no less than 100 μg/ml. For long term storage of the reconstituted solution it is recommended to add a carrier protein (0.1% HSA or BSA).
||>95% by SDS-PAGE
||Preservative: NoneConstituents: 10mM Acetic acid, pH 5.0
||The lyophilized protein is stable for a few weeks at room temperature, but best stored at -20°C.
