THP-1 nuclear extract
背景资料：THP-1 nuclear extract was prepared from a cell culture of the human acute monocytic leukemia THP-1 cell line. The THP-1 cell line was originally derived from the peripheral blood of a 1 year old boy with acute monocytic leukemia. THP-1 cells share similar properties to human monocyte-derived macrophages. These cells differentiate into mature macrophages (phagocytes) when grown in the presence of DMSO or phorbol 12-myristate 13-acetate (TPA or PMA). When stimulated with DMSO or vitamin D3, THP-1 cells adhere to the walls of cell culture flasks, and are therefore frequently utilized as in vitro model systems to study foam cell formation in relation to atherosclerosis. The THP-1 cell line is characterized by the expression of Fc and C3b receptors, the production of IL-1, and the lack of expression of cytoplasmic and surface immunoglobulins. In addition, these cells are phagocytic, produce lysosymes and stain positive for alpha-napthyl butyrate esterase. Because of these properties, they are often used in research to study monocyte differentiation.
产品描述：
THP-1 nuclear extract is recommended for use in studies related to 1) blood monocytes, 2) monocyte differentiation and 3) atherosclerosis.
产品应用：
THP-1 nuclear extract is supplied in Dilution Buffer (20 mM Hepes (pH 7.9), 100 mM KCl, 1 mM MgCl2, 20% glycerol, 0.5 mM PMSF and 0.5 mM DTT).
产品使用：
Extracts have been quality control tested by Western blot and TransAM® Transcription Factor ELISAs.
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。 |
