{"product_id":"cst-70247sf","title":"CST,  70247SF, MDR1\/ABCB1 (E1Y7S) Rabbit Monoclonal Antibody (BSA and Azide Free)","description":"Monoclonal Antibody for studying ABCB1. Validated for Western Blotting,Immunohistochemistry (Paraffin). Highly specific and rigorously validated in-house, MDR1\/ABCB1 (E1Y7S) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #70247) is ready to ship.\n\n\u003cb\u003eProduct Usage Information\u003c\/b\u003e\nThis product is the carrier free version of product #13978. 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 # 13978\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\nMDR1\/ABCB1 (E1Y7S) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of total MDR1 protein.\nSpecies Reactivity: Human, Mouse, Rat\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nMonoclonal antibody is produced by immunizing animals with recombinant protein surrounding Ala650 of human MDR1 protein.\n\u003cb\u003eBackground\u003c\/b\u003e\nMDR1\/ABCB1 belongs to the Mdr\/Tap subfamily of the ATP-binding cassette transporter superfamily (1). Multidrug resistance 1 (MDR1) serves as an efflux pump for xenobiotic compounds with broad substrate specificity. MDR1 substrates include therapeutic agents such as actinomycin D, etoposide, imatinib, and doxorubicin, as well as endogenous molecules including β-amyloids, steroid hormones, lipids, phospholipids, cholesterol, and cytokines (2). Research studies have shown that MDR1 reduces drug accumulation in cancer cells, allowing the development of drug resistance (3-5). On the other hand, MDR1 expressed in the plasma membrane of cells in the blood-brain, blood-cerebral spinal fluid, or blood-placenta barriers restricts the permeability of drugs into these organs from the apical or serosal side (6,7). MDR1 is also expressed in normal tissues with excretory function such as small intestine, liver, and kidney (7). Intracellular MDR1 has been detected in the ER, vesicles, and nuclear envelope, and has been associated with cell trafficking machinery (8). Other reported functions of MDR1 include viral resistance, cytokine trafficking (9,10), and lipid homeostasis in the peripheral and central nervous system (11-13).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nABC20; ABCB1; ATP binding cassette subfamily B member 1; ATP-binding cassette sub-family B member 1; ATP-binding cassette, sub-family B (MDR\/TAP), member 1; ATP-binding cassette, subfamily B, member 1; ATP-dependent translocase ABCB1; CD243; CLCS; colchicin sensitivity; doxorubicin resistance; GP170; MDR1; MGC163296; Multidrug resistance protein 1; P-glycoprotein 1; P-GP; PGY1; Phospholipid transporter ABCB1\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 130-180\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799866855593,"sku":"70247SF","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-70247sf","provider":"Iright","version":"1.0","type":"link"}
