COS-7细胞核提取物 货号:E-36079
COS-7 nuclear extract
背景资料:COS-7 nuclear extract was prepared from subconfluent undifferentiated cell cultures of the Simian kidney fibroblast COS-7 cell line. The COS-7 cell line was derived from immortalizing the African green monkey CV-1 cell line by transformation with an origin-defective mutant of the SV40 viral genome that is replication-deficient but produces wild-type large T antigen. The large T antigen supports replication and lytic growth of the SV40 virus as well as replication of SV40 promoter-containing plasmids. In addition to supporting propagation of the Simian SV40 virus, the COS-7 cell line is most commonly used in research related to replication and in transfection studies for the production of recombinant proteins.
产品描述:
COS-7 nuclear extract is specifically recommended for analysis of replication and for transfection studies.
产品应用:
COS-7 nuclear extract is supplied in lysis buffer (20 mM Hepes (pH 7.5), 400 mM NaCl, 20% glycerol, 0.1 mM EDTA, 10 mM NaF, 10 µM Na2MoO4, 1 mM NaVO3, 10 mM PNPP, 10 mM beta-glycerophosphate, 1 mM DTT and protease inhibitors).
产品使用:
Extracts have been quality control tested by Western blot.
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。 |
