准确的蛋白质定量对于许多细胞机制研究是必不可少的。现有技术依赖于外部样品评估,其需要大量样品以及添加测定特异性试剂,并且重要的是,是最终分析。这项研究利用了荧光分子转子的独特化学特征,该转子在扭曲到非扭曲状态之间波动,随后荧光强度根据环境条件(例如,粘度)。在这里,我们报告了一个快速,灵敏的原位蛋白定量方法,使用ARCAM-1,一个代表性的荧光分子转子,可用于非终端和终端检测的发展。
Accurate protein quantitation is essential for many cellular mechanistic studies. Existing technology relies on extrinsic sample evaluation that requires significant volumes of sample as well as addition of assay-specific reagents and importantly, is a terminal analysis. This study exploits the unique chemical features of a fluorescent molecular rotor that fluctuates between twisted-to-untwisted states, with a subsequent intensity increase in fluorescence depending on environmental conditions (e.g., viscosity). Here we report the development of a rapid, sensitive in situ protein quantitation method using ARCAM-1, a representative fluorescent molecular rotor that can be employed in both non-terminal and terminal assays.
