Additional Information
Description 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.
BiologicalActivity Determined by the dose-dependent stimulation of the proliferation of human umbilical vein endothelial cells (HUVEC) using a concentration range of 0.2-0.4 ng/ml.
Authenticity Verified by N-terminal and Mass Spectrometry analyses (when applicable).
Endotoxin Endotoxin level is <0.1 ng/ µg of protein (<1EU/ µg).
Protein Content Verified by UV Spectroscopy and/or SDS-PAGE gel.
Storage-20°C
PrecautionsRecombinant Human VEGF 121 is for research use only and not for use in diagnostic or therapeutic procedures.
