荧光寿命成像 (FLIM) 技术平台旨在读出福斯特共振能量转移 (FRET) 效率的变化,用于研究药物发现管道中的蛋白质相互作用。 FLIM 为药物发现提供了一种强大的、固有的比例成像方式,可以将相同的传感器结构从基于细胞的自动检测通过斑马鱼等小型透明生物转化为哺乳动物。为此,描述了自动 FLIM 多孔板读取器,用于固定细胞和活细胞的高内涵分析、斑马鱼的断层扫描 FLIM 以及通过共焦内窥镜对活细胞进行 FLIM FRET。对于基于细胞的测定,提出了使用 FLIM FRET 读出蛋白质聚集的示例应用,并说明了显微镜中同时进行多个 FLIM (FRET) 读出的潜力。
A fluorescence lifetime imaging (FLIM) technology platform intended to read out changes in Förster resonance energy transfer (FRET) efficiency is presented for the study of protein interactions across the drug-discovery pipeline. FLIM provides a robust, inherently ratiometric imaging modality for drug discovery that could allow the same sensor constructs to be translated from automated cell-based assays through small transparent organisms such as zebrafish to mammals. To this end, an automated FLIM multiwell-plate reader is described for high content analysis of fixed and live cells, tomographic FLIM in zebrafish and FLIM FRET of live cells via confocal endomicroscopy. For cell-based assays, an exemplar application reading out protein aggregation using FLIM FRET is presented, and the potential for multiple simultaneous FLIM (FRET) readouts in microscopy is illustrated.
