Validated for Western Blotting,Simple Western™. Highly specific and rigorously validated in-house, Phospho-FGF Receptor (Tyr653\/654) Antibody (CST #3471) is ready to ship.\n\n\u003cb\u003eProduct Usage Information\u003c\/b\u003e\nWestern Blotting: 1:1000\nSimple Western™: 1:10 - 1:50\n\u003cb\u003eStorage\u003c\/b\u003e\nSupplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg\/ml BSA and 50% glycerol. Store at -20°C. Do not aliquot the antibody.\n\u003cb\u003eProtocol\u003c\/b\u003e\nAvailable protocols: Western Blotting\n\u003cb\u003eSpecificity \/ Sensitivity\u003c\/b\u003e\nPhospho-FGF Receptor (Tyr653\/654) Antibody detects endogenous levels of FGF receptors only when phosphorylated at tyrosines 653\/654. This antibody detects phosphorylated FGF Receptors 2 and 4 when expressed exogenously. Based on sequence comparisons, reactivity with FGF Receptor 3 is possible but has not been experimentally confirmed. This antibody also cross-reacts with activated PDGF receptor and insulin\/IGF-I receptors.\nSpecies Reactivity: Human\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nPolyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Tyr653\/654 of human FGFR-1 (the corresponding sequence is the same in FGFR-2, -3 and -4). Antibodies are purified by protein A and peptide affinity chromatography.\n\u003cb\u003eBackground\u003c\/b\u003e\nFibroblast growth factors (FGFs) produce mitogenic and angiogenic effects in target cells by signaling through cell surface receptor tyrosine kinases. There are four members of the FGF receptor family: FGFR1 (flg), FGFR2 (bek, KGFR), FGFR3, and FGFR4. Each receptor contains an extracellular ligand-binding domain, a transmembrane domain, and a cytoplasmic kinase domain (1). Following ligand binding and dimerization, the receptors are phosphorylated at specific tyrosine residues (2). Seven tyrosine residues in the cytoplasmic tail of FGFR1 can be phosphorylated: Tyr463, 583, 585, 653, 654, 730, and 766. Tyr653 and Tyr654 are important for catalytic activity of activated FGFR and are essential for signaling (3). The other phosphorylated tyrosine residues may provide docking sites for downstream signaling components, such as Crk and PLCÎ³ (4,5).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nBasic fibroblast growth factor receptor 1; bFGF-R-1; BFGFR; CD331; CEK; ECCL; FGFBR; FGFR-1; FGFR1; FGFR1\/PLAG1 fusion; Fibroblast growth factor receptor 1; FLG; FLJ99988; FLT-2; FLT2; Fms-like tyrosine kinase 2; fms-related tyrosine kinase 2; HBGFR; heparin-binding growth factor receptor; HH2; HRTFDS; hydroxyaryl-protein kinase; KAL2; N-SAM; OGD; Proto-oncogene c-Fgr; soluble FGFR1 variant 1; soluble FGFR1 variant 2\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 120,  145\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46799421833385,"sku":"3471S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/cst-3471s","provider":"Iright","version":"1.0","type":"link"}
