{"product_id":"cst-6509s","title":"CST,  6509S, SignalSilence® Ezh2 siRNA I","description":"siRNA for studying EZH2 in the research area.\n\n\u003cb\u003eProduct Usage Information\u003c\/b\u003e\nCST recommends transfection with 100 nM SignalSilence ® Ezh2 siRNA I 48 to 72 hours prior to cell lysis. For transfection procedure, follow protocol provided by the transfection reagent manufacturer. Please feel free to contact CST with any questions on use. Each vial contains the equivalent of 100 transfections, which corresponds to a final siRNA concentration of 100 nM per transfection in a 24-well plate with a total volume of 300 μl per well.\n\u003cb\u003eStorage\u003c\/b\u003e\nSignalSilence ® siRNA is supplied in RNAse-free water. Aliquot and store at -20ºC.\n\u003cb\u003eBackground\u003c\/b\u003e\nThe polycomb group (PcG) proteins are involved in maintaining the silenced state of several developmentally regulated genes and contribute to the maintenance of cell identity, cell cycle regulation, and oncogenesis (1,2). Enhancer of zeste homolog 2 (Ezh2), a member of this large protein family, contains four conserved regions, including domain I, domain II, and a cysteine-rich amino acid stretch that precedes the carboxy-terminal SET domain (3). The SET domain has been linked with histone methyltransferase (HMTase) activity. Moreover, mammalian Ezh2 is a member of a histone deacetylase complex that functions in gene silencing, acting at the level of chromatin structure (4). Ezh2 complexes methylate histone H3 at Lys9 and 27 , which is thought to be involved in targeting transcriptional regulators to specific loci (5). Ezh2 is deregulated in various tumor types, and its role, both as a primary effector and as a mediator of tumorigenesis, has become a subject of increased interest (6).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\npolycomb repressive complex; PRC2\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H","brand":"CST","offers":[{"title":"Default Title","offer_id":46800790323369,"sku":"6509S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-6509s","provider":"Iright","version":"1.0","type":"link"}
