Disclosed is a novel diagnostic reagent system for the detection of hydroperoxides or substances which react with peroxidatively active substances resulting in the liberation of hydroperoxides which reagent system comprises a chromogenic oxidation indicator and a peroxidase or a peroxidatively active substance, together with an inhibitor of color generation selected from the group of 1,4-disubstituted semicarbazides, thiosemicarbazides and 1,5-disubstituted carbazides as inhibitors of color generation. By inhibiting the generation of color formed by oxidation of the chromogenic indicator, the indicator's usefulness in discriminating between varying concentrations of analyte is enhanced.
本发明公开了一种新型诊断试剂系统,用于检测氢过氧化物或与过氧化活性物质发生反应导致氢过氧化物释放的物质,该试剂系统包括一个发色性氧化指示剂和一个过氧化物酶或一种过氧化活性物质,以及一种发色抑制剂,该抑制剂选自作为发色抑制剂的 1,4-二取代半咔嗪类、硫代氨基咔嗪类和 1,5-二取代咔嗪类。通过抑制由发色指示剂氧化形成的颜色的生成,可提高指示剂在区分不同浓度的分析物方面的作用。
