Quality Standard:【产品介绍】The expression of VEGF and KDR correlates
highly with the normal ocular vascularization in humans,
but VEGF may also be necessary for nonvascular
retinal developmental functions, especially for
the coordination of neural retinal development and
the preliminary steps of the establishment of the
definitive stable retinal vasculature (1). KDR/flk-1 is
one of two receptors for vascular endothelial growth
factor, a potent angiogenic peptide. KDR/flk-1 is an
early marker for endothelial cell progenitors, and
its expression is restricted to endothelial cells in
vivo (2). Therapeutic angiogenesis is likely to require
the administration of factors that complement each
other. Activation of the receptor tyrosine kinase
KDR/Flk1 by vascular endothelial growth factor (VEGF)
is crucial, but molecular interactions of other factors
with VEGF and Flk1 have been studied to a limited
extent. Activation of KDR/Flt1 by PGF resulted
in intermolecular transphosphorylation of Flk1,
thereby amplifying VEGF-driven angiogenesis
through KDR/Flk1. Even though VEGF and PGF both
bind KDR/Flt1, PGF uniquely stimulated the
phosphorylation of specific KDR/Flt1 tyrosine residues
and the expression of distinct downstream target genes (3).

Products Data
A. Western blot analysis on human placenta lysate
using anti-KDR/VEGFR-2 RabMAb (cat. # 2296-1),
dilution 1:500.
Specificity
A recombinant protein corresponding to residues in
the extracellular domain of human KDR/VEGFR2 was used as
an immunogen. It is predicted that this antibody does
not cross react with other members of the VEGF
receptor family.
