Western blot image of human umbilical vein endothelial cells stimulated with pervanadate (1 mM) for 30 min. then the blots were untreated (lanes 1 & 3) or treated with alkaline phosphatase (lanes 2 & 4). The blots were probed with rabbit polyclonal anti-VE-cadherin (Tyr-685) (lanes 1 & 2) or mouse monoclonal anti-VE-cadherin (lanes 3 & 4).
Bulk Order Anti-VE-Cadherin (Tyr-685), Phosphospecific Antibody
Cadherins are transmembrane glycoproteins vital in calcium-dependent cell-cell adhesion during tissue differentiation. Cadherins cluster to form foci of homophilic binding units. A key determinant to the strength of the cadherin-mediated adhesion may be by the juxtamembrane region in cadherins. VE-cadherin (Cadherin 5) is the major cadherin found in endothelial cells and has important roles during angiogenesis and maintenance of barrier permeability. The cytoplasmic domain of VE-cadherin comprises the juxtamembrane domain that binds to the p120 catenin, and the carboxylterminal domain that interacts with β- or γ-catenins. Modulation of tyrosine phosphorylation on one or more of the nine tyrosine sites in the cytoplasmic domain may be important for regulating both angiogenesis and permeability. Phosphorylation of Tyr-658 and Tyr-731 alters catenin binding, restores cell migration, and decreases barrier permeability. While VEGF-induced phosphorylation of Tyr-685 occurs through c-Src, and regulates endothelial cell migration, but not permeability
Antigen Affinity Purified
Phospho-VE-Cadherin (Tyr-685) synthetic peptide (coupled to carrier protein) corresponding to amino acids surrounding tyrosine 685 in human VE-cadherin. This sequence has significant homology to the conserved site in rat and mouse VE-cadherin, but is not conserved in other cadherins.
Human, Mouse, Rat
Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol
This antibody was cross-adsorbed to an unrelated phospho-tyrosine peptide and unphosphorylated VE-cadherin (Tyr-685) peptide before affinity purification using phospho-VE-cadherin (Tyr-685) peptide. The purified antibody detects a 140 kDa* band corresponding to VE-cadherin in western blots of human endothelial cells treated with pervanadate, and this band is not detected in untreated cells or after alkaline phosphatase treatment.
