Fluorescent Chromeo™ Py-Dyes
背景资料:Chromeo Py-Dyes have been shown to work efficiently and with high sensitivity in different methods of protein electrophoresis. Proteins labeled with pyrylium dyesmaintain their native charge and isoelectric points, which results in sharp and characteristic bands during electrophoresis. For your convenience, Chromeo Py-Dyes are also included in our complete Capillary Electrophoresis (CE) Dye Kits, containing optimized and quality-controlled buffer systems.
产品描述:Chromeo™ Py-Dyes are a unique class of amine-reactive pyrylium dyes that change their color and become fluorescent upon reacting with primary amines. The shift in absorption and the induction of fluorescence effectively eliminate background effects from any unbound dye. The labeled proteins are ready to use immediately, and as the labeling method is fast, easy & reproducible, Chromeo Py-Dyes are suitable for a variety of “no-wash” applications:
Pre- and post-stain in SDS-protein electrophoresis
Pre-stain in capillary electrophoresis (CE)
Pre-stain in capillary isoelectric focusing (IEF)
Pre-stain in 2D capillary electrophoresis
Label for carbohydrate characterization
Small size label of proteins
Reagent to monitor amino functionalities on various surfaces
产品应用:Pyrylium dyes change their color and fluorescent properties upon reacting with proteins. After binding to primary amines, they undergo a large shortwave spectral shift that is visible to the naked eye (Figure 1). There is also a large increase in quantum yield that changes the non- or only weakly fluorescent dye into a bright fluorescent conjugate. (See the Properties tab for detailed information on each Py-Dye).
产品使用:
Chromeo™ Py-Dye advantages
No washing steps required
No background from unbound dye
Fast and simple procedure
Small size
No change in net charge of the labeled molecule
No interference of excitation and emission wavelength
Because of their unique features, Chromeo Py-Dyes (Chromeo P429, P456, P503, P540 and P543) have been used successfully in a number of “no-wash” applications such capillary electrophoresis, SDS-protein gel electrophoresis, isoelectric focusing or as a label in receptor binding studies. See the Product Citations tab for a sample of published references.
文献参考:
Amine-reactive pyrylium dyes have been used as a pre-stain in protein electrophoresis. The high sensitivity with a detection-limit of 16 picograms and the fast, reproducible procedure improve electrophoresis results compared to other commercially available stains like SYPRO Red or silver staining.

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。 |
