The Angiogenesis Receptor Tyrosine Kinase Antibody Sampler Kit provides an economical means of detecting the activation of VEGF receptor 2, FGF receptor 1, PDGF receptor beta, Tie2, and VEGF-A using phospho-specific and control antibodies. The kit includes enough antibodies to perform two western blot experiments with each primary antibody.

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Background

Angiogenesis is defined as the physiological process by which new blood vessels are formed from pre-existing blood vessels. It is a critical process that enables specific physiological conditions in healthy adults, including development, skeletal muscle hypertrophy, and wound healing (1,2). Angiogenesis can be aberrantly activated to generate new blood vessels during pathological conditions such as cancer, neovascular disorders, and chronic inflammation. Angiogenesis is a complicated process regulated by multiple mechanisms and pathways (3). VEGFR2 is a member of the family of receptor tyrosine kinases (RTKs) mainly located in endothelial cells and is a major player in angiogenesis. VEGF-VEGFR2 ligand-receptor activation is the key signaling pathway for angiogenesis activation (4,5). Multiple non-VEGF RTK activations can replace VEGFR to promote angiogenesis (6,7), including PDGFR (9), FGFR (8), and Tie2 (10). These RTKs are targets for an antiangiogenic based disease treatment (11,12).
