General description
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。
Application
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。
