Sigma货号30693-1mg现货Chromeo™ P503上海睿安生物13611631389

属性

质量水平:100

荧光:λ_ex 503nm;λ_em 627nm±10 nm in 0.1M bicarbonate buffer pH 8.3

储存温度:−20°C

说明

一般描述: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>100nm，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。

应用: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。

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
Protein labeling enhances aptamer selection by methods of kinetic capillary electrophoresis.

Methods of kinetic capillary electrophoresis (KCE) facilitate highly ef_ficient 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

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
