    Compositions and methods for detecting the activity of an ion channel in a cell are described. The methods include providing a loading buffer solution to the cell, where the loading buffer includes a thallium ion indicator and optionally chloride ions, and providing a stimulus buffer that includes thallium ions to the cell. Providing the stimulus buffer can cause thallium ion influx into or efflux out of the cell through the ion channel. After providing the stimulus buffer, a change in at least one optical property of the thallium ion indicator is detected in response to thallium influx or efflux, thereby detecting the activity of the ion channel.

  • Fluorinated xanthene derivatives
    申请人:Molecular Probes, Inc.
    公开号:US06162931A1
    公开(公告)日:2000-12-19
    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.
    该发明的染料家族是直接在一个或多个芳香碳上被取代的荧光素和罗丹素。这些取代的荧光染料具有更高的光稳定性,在生理范围为6-8的pH变化下比非染料具有较低的敏感性,当与物质结合时表现出较少的猝灭,并具有额外的优势。该发明的染料可用作可检测的示踪剂,并用于制备有机和无机物质的共轭物。

  • Synthesis of Fluorinated Fluoresceins
    作者:Wei-Chuan Sun、Kyle R. Gee、Dieter H. Klaubert、Richard P. Haugland

    日期:1997.9.1
    Several novel fluorinated fluoresceins (Oregon Green dyes) were prepared by the reaction of fluororesorcinols with phthalic anhydride and its derivatives. A novel regiospecific synthesis of fluororesorcinols was key to the successful synthesis of these new fluorophores. (Polyfluoro)-nitrobenzenes were reacted with 2 equiv of sodium methoxide followed by reduction, hydrodediazoniation, and demethylation, giving the first straightforward synthesis of 2-fluororesorcinol, 4-fluororesorcinol, 2,4-difluororesorcinol, and 2,4,5-trifluororesorcinol. These fluorinated fluoresceins have higher photostability and ionize at a lower pH (pK(a) = 3.3-6.1) than fluorescein (pK(a) = 6.5). Some of the fluorinated fluoresceins have very high quantum yields (0.85-0.97), which, in combination with their lower pK(a)s and high photostability, makes them superior fluorescent dyes for use as reporter molecules in biological systems.
