Fluorescent-labeled Recombinant Proteins  (荧光标记蛋白)

荧光标记蛋白质是与荧光染料共价结合的蛋白质分子。荧光标记通常作为研究构象动力学和分子相互作用的工具，或跟踪蛋白质的运动，以了解其生物学功能。荧光分析可以实时在溶液中进行，具有高的时间分辨率，灵敏度可达到单分子级别。

Fluorescent-labeled proteins are protein molecules that covalently binding with fluorescent dyes. The fluorescent label (fluorescent tag, fluorescent probe) generally acts as a tool to investigate conformational dynamics and molecular interactions or track the movement of proteins in order to gain insight into their biological functions. + Fluorescent assays can be performed in real-time, in solution, with high-time resolution and sensitivity down to single molecules.
