Validated for Western Blotting,ELISA+. Highly specific and rigorously validated in-house, Phospho-BCKDH-E1 alpha (Ser293) (E2V6B) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #91687) is ready to ship.\n\n\u003cb\u003eProduct Usage Information\u003c\/b\u003e\nThis product is the carrier free version of product #40368. 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 # 40368\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-BCKDH-E1 alpha (Ser293) (E2V6B) Rabbit Monoclonal Antibody recognizes endogenous levels of BCKDH-E1α protein only when phosphorylated at Ser292 of mature human BCKDH-E1α, Ser293 of mature mouse BCKDH-E1α, or Ser293 of mature rat BCKDH-E1α.\nSpecies Reactivity: Human, Mouse, Rat, Monkey\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nMonoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser292 of mature human BCKDH-E1α protein, which corresponds to Ser293 of mature mouse BCKDH-E1α protein and Ser293 of mature rat BCKDH-E1α protein.\n\u003cb\u003eBackground\u003c\/b\u003e\nBranched-chain amino acids (BCAAs) leucine, isoleucine, and valine are essential amino acids in mammals, but elevated levels of BCAAs have been implicated in cardiovascular and metabolic disorders (1). The branched-chain α-keto acid dehydrogenase complex (BCKDH) catalyzes the rate-limiting step in the BCAA degradation pathway (2,3). Branched-chain α-keto acid decarboxylase (BCKDH-E1) is one of three enzymatic components in this complex (3). The α subunit of BCKDH-E1 (BCKDH-E1α) is critical for the regulation of BCKDH. Phosphorylation of BCKDH-E1α was shown to play a key role in regulating the enzymatic activity of this complex (3-5). Phosphorylation of BCKDH-E1α at Ser293 inactivates BCKDH (3,4). A significant elevation in plasma BCAA levels was reported to correlate with increased phosphorylation of BCKDH-E1α at Ser293 and suppressed BCKDH activity in the liver of diabetic mice (5).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\n2-oxoisovalerate dehydrogenase (lipoamide); 2-oxoisovalerate dehydrogenase subunit alpha, mitochondrial; BCKDE1A; BCKDH E1-alpha; BCKDHA; branched chain keto acid dehydrogenase E1 alpha protein; branched chain keto acid dehydrogenase E1 subunit alpha; branched chain keto acid dehydrogenase E1, alpha polypeptide; Branched-chain alpha-keto acid dehydrogenase E1 component alpha chain; FLJ45695; MSU; MSUD1; ODBA; OVD1A\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk\nSENSITIVITY: Endogenous\nMW (kDa): 49\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800008446121,"sku":"91687SF","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-91687sf","provider":"Iright","version":"1.0","type":"link"}
