{"product_id":"cst-52911sf","title":"CST,  52911SF, Phospho-NPM1 (Thr199) (E4C7S) Rabbit Monoclonal Antibody (BSA and Azide Free)","description":"Monoclonal Antibody for studying NPM1 (Thr199) phosphate. Validated for Western Blotting,Immunohistochemistry (Paraffin). Highly specific and rigorously validated in-house, Phospho-NPM1 (Thr199) (E4C7S) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #52911) is ready to ship.\n\n\u003cb\u003eProduct Usage Information\u003c\/b\u003e\nThis product is the carrier free version of product #75984. 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 # 75984\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-NPM1 (Thr199) (E4C7S) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of NPM1 protein only when phosphorylated at Thr199.\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 Thr199 of human NPM1 protein.\n\u003cb\u003eBackground\u003c\/b\u003e\nNucleophosmin (NPM1), also known as B23, numatrin, or NO38, is an abundant phosphoprotein primarily found in nucleoli. It has been implicated in several distinct cellular functions, including assembly and transport of ribosomes, cytoplasmic\/nuclear trafficking, regulation of DNA polymerase α activity, centrosome duplication, and molecular chaperoning activities (1,2). The gene is also known for its fusion with the anaplastic lymphoma kinase (ALK) receptor tyrosine kinase. The NPM1 portion contributes to transformation by providing a dimerization domain, which activates the fused kinase (3,4).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nB23; MGC104254; NPM; NPM1; Nucleolar phosphoprotein B23; Nucleolar protein NO38; Nucleophosmin; nucleophosmin (nucleolar phosphoprotein B23, numatrin); nucleophosmin 1; nucleophosmin\/nucleoplasmin family, member 1; Numatrin; testicular tissue protein Li 128\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 38\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799794831529,"sku":"52911SF","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-52911sf","provider":"Iright","version":"1.0","type":"link"}
