一般說明
Chromeo P503通过与伯胺结合后颜色从蓝色变为红色来标记蛋白质和肽。Chromeo P503显示弱荧光，量子产率为<1% in solution. After conjugation to a primary amine group, the label undergoes a shortwave spectral shift of >100 nm，量子产率提高到50%。该特性可对伯胺、蛋白质和其他生物分子进行独特的检测。
應用
Chromeo P503用作荧光试剂，并用于标记分子（如蛋白质）内的伯胺基团。Chromeo P503标记的蛋白质可以在各种凝胶电泳和色谱应用中进行研究。
注意
为保证稳定性，冻干染料应避光保存于4℃。本产品自到货之日起保修6个月。

CIEF and CZE are coupled with LIF detection to create an ultrasensitive 2-D separation method for proteins. In this method, two capillaries are joined through a buffer-filled interface. Separate power supplies control the potential at the injection end of the

We have coupled CIEF with an LIF detector that is based on a post-column sheath flow cuvette. We employed Chromeo P503 as a fluorogenic reagent to label proteins before analysis. This reagent reacts with the epsilon-amine of lysine residues, preserving

The spectroscopic and electrophoretic properties of proteins labeled with Chromeo P503 were investigated. Its photobleaching characteristics were determined by continually infusing Chromeo P503-labeled alpha-lactalbumin into a sheath-flow cuvette and monitored fluorescence as a function of laser power. The labeled protein

Methods of kinetic capillary electrophoresis (KCE) facilitate highly efficient selection of DNA aptamers for protein targets. The inability to detect native proteins at low concentrations in capillary electrophoresis creates, however, a significant obstacle for many important protein targets. Here we
