Recombinant Human VEGF-B


 
		Synonyms :
Vascular Endothelial Growth Factor-B, VEGF-related factor, VRF
		Description :
VEGF-B, a member of the VEGF family, is a potent growth and angiogenic cytokine.  It promotes DNA synthesis in endothelial cells, helps regulate angiogenesis and vascular permeability, and inhibits apoptosis in certain smooth muscle cells and neurons.  VEGF-B is expressed in all tissues except the liver.  It forms cell surfaced-associated disulfide linked homodimers and can form heterodimers with VEGF-A.  There are two known isoforms, formed by alternative splicing, which have been designated VEGF-B167 and VEGF-B186.  Both forms have identical amino-terminal sequences encoding a “cysteine knot” like structural motif, but differ in their carboxyl-terminal domains.  Both VEGF-B isoforms signal only through the VEGFR1 receptor.  Recombinant human VEGF-B is a 38.0 kDa disulfide-linked homodimeric protein consisting of two 167 amino acid polypeptide chains.

100-20B
		Source :
E.coli
		Purity :
Greater than 98% by SDS-PAGE gel and HPLC analyses.
		Endotoxin Level :
Endotoxin level is less than 0.1 ng per μg (1EU/μg).
		Biological Activity :
Determined by the dose-dependent stimulation of the proliferation of human umbilical vein endothelial cells (HUVEC) in the presence of human VEGF165.  The expected ED50 for this effect is 1.0-2.0 μg/ml.
