Capillary Electrophoresis (CE) Dye Kits
背景资料:The CE Dye Kits provide a convenient alternative for the fluorescent labeling of protein samples prior to capillary electrophoresis. Capillary electrophoresis (CE) has proven to be a useful tool in modern cell biology applications because it enables the rapid and high-resolution separation of proteins in a microsample format. These properties have made CE especially useful when performing single-cell protein analyses. However, traditional CE performed using UV absorbance can suffer from a lack of sensitivity due to the short path length across the capillary.
产品描述:CE Dyes overcome a large limitation associated with derivatization-based methods for labeling proteins because the positive charge of the amine group is maintained even after dye conjugation (Figure 1). This means that every protein labeled with CE Dye maintains its native charge, so you get single peak protein detection. With CE Dyes, there is no band broadening or need to perform adjusted ionic character calculations.
产品应用:CE Dye Kits provide a highly sensitive, convenient solution for capillary electrophoresis (CE). Upon binding to protein, CE Dyes undergo a large Stokes shift as well as a 50-fold increase in quantum yield. The result is sensitive detection with minimal background.
产品使用:
The CE Dye advantage
User-friendly, non-toxic labeling
Large Stokes shift for reduced background
Fast and simple procedure
Sensitive protein detection
文献参考:
CE Dyes have been successfully used as a stain in capillary electrophoresis. The detection limit in the picomolar range, the fast reaction time and the preservation of the protein’s native charge make our CE Dyes an interesting alternative to commonly used detection techniques.

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。 |
