    A Design of Fluorescent Probes for Superoxide Based on a Nonredox Mechanism
    摘要:
    Fluorometric detection of O2-* is performed based on desulfonylation of 3 to the corresponding fluoresceins 4 through nucleophilic substitution, and this fluorescing process is quite specific toward O2-* over H2O2, t-BuOOH, NaOCl, 1O2, HO*, NO*, and ONOO-. Furthermore, effects of glutathione, cytochrome P450 reductase/NADPH, and diaphorase/NADH are relatively small on the fluorescing process of probe 3 with X = Y = F, which is useful to detect O2-* released from neutrophils stimulated by phorbol myristate acetate with satisfactory sensitivity.

  • Fluorinated xanthene derivatives
    申请人:Molecular Probes, Inc.
    公开号:EP1441010A1
    公开(公告)日:2004-07-28
    The family of dyes of the invention are fluoresceins and rhodols that are directly substituted on one or more aromatic carbons by fluorine. These fluorine-substituted fluorescent dyes possess greater photostability and have lower sensitivity to pH changes in the physiological range of 6-8 than do non-fluorinated dyes, exhibit less quenching when conjugated to a substance, and possess additional advantages. The dyes of the invention are useful as detectable tracers and for preparing conjugates of organic and inorganic substances.
    本发明的染料系列是在一个或多个芳香碳上直接被氟取代的荧光素和荧光铑。与非氟化染料相比,这些氟取代的荧光染料具有更高的光稳定性,在 6-8 生理范围内对 pH 值变化的敏感性较低,与物质共轭时淬灭程度较低,并具有其他优点。本发明的染料可用作可检测的示踪剂,也可用于制备有机和无机物质的共轭物。
  • Composition and method for measuring thallium influx and efflux
    申请人:Life Technologies Corporation
    公开号:EP2562543A1
    公开(公告)日:2013-02-27
    The present invention relates to methods for detecting the activity of an ion channel in a cell. The methods comprise providing a loading buffer solution to a cell that has an ion channel. The loading buffer comprises at least one thallium indicator (e.g., an environmentally sensitive, luminescent dye) and a physiological concentration of chloride ions. The methods further comprise providing a stimulus buffer to the cell, wherein the stimulus buffer comprises thallium (e.g., thallium ions). Providing the stimulus buffer causes thallium influx into the cell through the ion channel. After providing the stimulus buffer, the luminescence (e.g., fluorescence) of the dye in the cell is detected. The luminescence of the dye can change in the presence or absence of thallium. The methods may be used to measure influx or efflux of thallium through an ion channel.
    本发明涉及检测细胞中离子通道活性的方法。这些方法包括向具有离子通道的细胞提供上载缓冲溶液。上载缓冲液包括至少一种铊指示剂(例如,环境敏感的发光染料)和生理浓度的氯离子。所述方法还包括向细胞提供刺激缓冲液,其中刺激缓冲液包括铊(如铊离子)。提供刺激缓冲液会导致铊通过离子通道流入细胞。提供刺激缓冲液后,检测细胞中染料的发光(如荧光)。铊存在或不存在时,染料的发光会发生变化。这些方法可用于测量铊通过离子通道的流入或流出。
