2-Thiazolyl tetrazolium salt compounds characterized by a reflectance spectrum exhibiting an extended plateau above about 600-650 nm. Such compounds are useful as chromogenic indicators for reducing substances such as NADH. The reflectance plateau confers improved accuracy to analytical assays, particularly for the determination of analytes of medical diagnostic significance, in which a colorimetric response on a reagent carrier matrix is measured by reflectance.
2-Thiazolyl tetrazolium salt(2-
噻唑基
四氮唑盐)化合物,其特征是反射光谱在约 600-650 纳米波长以上表现出延伸的高原。此类化合物可用作还原性物质(如
NADH)的显色指示剂。反射高原提高了分析测定的准确性,特别是在测定具有医疗诊断意义的分析物时,其中试剂载体基质上的比色反应是通过反射测定的。
