Validated for Western Blotting,ELISA+. Highly specific and rigorously validated in-house, Phospho-IRS-1 (Ser612) (L7B8) Mouse Monoclonal Antibody (BSA and Azide Free) (CST #15860) is ready to ship.\n\n\u003cb\u003eProduct Usage Information\u003c\/b\u003e\nThis product is the carrier free version of product #3193. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol. This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT\u0026amp;RUN or CUT\u0026amp;Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us . Optimal dilutions\/concentrations should be determined by the end user. BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity.\n\u003cb\u003eFormulation\u003c\/b\u003e\nSupplied in 1X PBS (10 mM Na 2 HPO 4 , 3 mM KCl, 2 mM KH 2 PO 4 , and 140 mM NaCl (pH 7.8)). BSA and Azide Free. For standard formulation of this product see product # 3193\n\u003cb\u003eStorage\u003c\/b\u003e\nStore at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze\/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance.\n\u003cb\u003eSpecificity \/ Sensitivity\u003c\/b\u003e\nPhospho-IRS-1 (Ser612) (L7B8) Mouse Monoclonal Antibody (BSA and Azide Free) detects endogenous IRS-1 only when phosphorylated at serine 612.\nSpecies Reactivity: Human, Mouse, Rat\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nMonoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser612 of mouse IRS-1.\n\u003cb\u003eBackground\u003c\/b\u003e\nInsulin receptor substrate 1 (IRS-1) is one of the major substrates of the insulin receptor kinase (1). IRS-1 contains multiple tyrosine phosphorylation motifs that serve as docking sites for SH2-domain containing proteins that mediate the metabolic and growth-promoting functions of insulin (2-4). IRS-1 also contains over 30 potential serine\/threonine phosphorylation sites. Ser307 of IRS-1 is phosphorylated by JNK (5) and IKK (6) while Ser789 is phosphorylated by SIK-2, a member of the AMPK family (7). The PKC and mTOR pathways mediate phosphorylation of IRS-1 at Ser612 and Ser636\/639, respectively (8,9). Phosphorylation of IRS-1 at Ser1101 is mediated by PKCθ and results in an inhibition of insulin signaling in the cell, suggesting a potential mechanism for insulin resistance in some models of obesity (10).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nHIRS-1; Insulin receptor substrate 1; IRS-1; IRS1\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 180\nSource\/Isotype: Mouse IgG2a","brand":"CST","offers":[{"title":"Default Title","offer_id":46797628309673,"sku":"15860SF","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-15860sf","provider":"Iright","version":"1.0","type":"link"}
