重组 RXR-a 蛋白 货号：E-31133
Recombinant RXR-α protein
背景资料：RXR-α (Retinoid X Receptor alpha, NR2B1) is a nuclear receptor that mediates the biological effects of retinoids by its involvement in retinoic acid-mediated gene activation. RXR-α exerts its action by binding, as a homodimer or a heterodimer, to specific sequences in the promoters of target genes and regulating their transcription.RXR-α is a member of the steroid and thyroid hormone receptor superfamily of transcriptional regulators.
产品描述：
Recombinant RXR-α is isolated from an E. coli strain that carries the coding sequence of the human RXR-α under the control of a T7 promoter (accession number NM 002957). The purified recombinant protein has an amino terminal polyhistidine tag and is greater than 95% homogeneous and contains no detectable protease, DNase and RNase activity.
产品应用：
Recombinant RXR-α is suitable for in vitro transcription, chromatin remodeling and protein-protein interaction assays. 20 ng is sufficient for DNA-protein assays, 20-100 ng is sufficient for reconstituted transcription assays and 100 ng is sufficient for protein-protein interaction studies. The molecular weight of the protein is ~48 kDa. NOTE: The presence of Poly [d(I-C)] in buffers may affect protein functionality and should be avoided.
产品使用：
10 µg of Recombinant RXR-α protein and Dilution Buffer AM1 (20 mM Tris-Cl (pH 8), 20% glycerol, 100 mM KCl, 1 mM DTT and 0.2 mM EDTA). Protein is supplied at 0.5 µg/µl in Dilution Buffer AM1.
温度保存：
Lyophilized proteins can be stored at -20°C or -80°C, preferably desiccated. Recombinant proteins in solution are temperature sensitive and must be stored at -80°C to prevent degradation. Avoid repeated freeze/thaw cycles and keep on ice when not in storage.

关于5-hmC
5-hmC是近年来在动物组织中发现的，由胞嘧啶修饰而来。5-hmC在表观遗传学上的功能可能与5-甲基化胞嘧啶(5-mC)不同。尽管到现在为止还不确知其功能，有研究者猜测它在调控基因的表达与关闭过程中起着重要的作用。5-mC的发现让我们不得不重新评估DNA甲基信息，也不得不监测人类的健康组织和病理组织之间5-mC相对分布的差异。在EPI公司的MethylFlash技术之前，我们还没有发现任何直接的常规方法来检测5- hmC,以及区分5-hmC和5-mC
5-hmC 和 5-mC的区别
时下常用的DNA甲基化分析方法包括限制内切酶酶切和亚硫酸氢盐或MeDIP介导的MS-PCR和测序，这些技术都不适合用来检测5-hmC，因为它与5-mC事实上很难用这类方法区分开来。为了解决这个问题，EPIk研制了MethylFlash羟甲基化DNA定量试剂盒(荧光法)。本试剂盒提供了一种很经济的方法来检测5-羟甲基化胞嘧啶，并且区分5-hmC, 5-mC, 和 C，使得研究者能够重新评估他们的DNA甲基化信息，也能够在新样品中寻找DNA羟甲基化。 |
