Certain water-compatible reducible compounds are useful in analytical compositions and elements for assay of various analytes, for example, microorganisms. These compounds comprise a moiety which provides a detectable species (for example, a dye) when released from the compound at physiological pH. Further, these compounds are aromatic derivatives or quinones having water-compatibilizing substituents which allow them to be used in compositions without the use of surfactants.
某些与
水相容的还原性化合物可用于分析组合物和元素中,以检测各种分析物,例如微
生物。 这些化合物包含一个分子,当在生理 pH 值下从化合物中释放出来时,该分子可提供一种可检测的物质(例如
染料)。 此外,这些化合物是芳香族衍
生物或
醌类化合物,具有与
水相容的取代基,使其无需使用表面活性剂即可用于组合物中。
