Certain substituted benzo- and naphthoquinone electron transfer agents are useful in analytical compositions, elements and methods, e.g. for determinations of living cells. These electron transfer agents are capable of being reduced by an analyte, and the reduced electron transfer agent, in turn, reduces another compound providing a detectable species (e.g. a dye). The reduction potential (E1/2) of the electron transfer agents useful in this invention is in the range of from -320 to +400 mV as measured in an aqueous buffer solution at pH 7.
某些取代的苯醌和萘醌电子转移剂可用于分析组合物、元素和方法中,例如用于测定活细胞。这些电子转移剂能够被分析物还原,被还原的电子转移剂反过来会还原另一种化合物,从而提供可检测的物质(如染料)。本发明中电子转移剂的还原电位(E1/2)在 pH 值为 7 的缓冲水溶液中的测量范围为 -320 至 +400 mV。
