Fluorescent dyes with large Stokes shift play a key role in avoiding self-quenching and scattered light of dyes in the process of biological imaging. In this work, a novel mitochondria-targetable fluorescent dye (PI-C2) with large Stokes shift (e. g. Maximum value is 219 nm in DMSO) have been developed. Compared to the commercial mitochondria probes MTR and MTG (Less than 30 nm in various solution)
具有大斯托克斯位移的荧光染料在避免生物成像过程中染料的自猝灭和散射光方面起着关键作用。在这项工作中,已开发出一种具有大斯托克斯位移(例如,在DMSO中最大值为219 nm)的线粒体靶向荧光染料(PI-C2)。与市售的线粒体探针MTR和MTG(在各种溶液中小于30 nm)相比,新构建的PI-C2在各种解决方案中都有更大的斯托克斯位移(在各种解决方案中为169–219 nm)。此外,该探针可以成功地用于检测线粒体,并在不同的活细胞系中表现出优异的光稳定性。具有大Stokes的新型荧光平台可以扩展以构建具有大Stokes位移的强大荧光探针,用于检测线粒体中的多种生物分子。
