@ Ferric ion chelates are useful in analytical compositions, elements and methods for the determination of reductants, or other analytes which can react to produce a reductant. The ferric ion chelate is reduced to ferrous ion and ferric ion coordinating ligand. The ferrous ions then coordinate with a suitable ferrous ion coordinating ligand to form a colored complex. In particular, these compositions and elements are useful for detecting nicotinamide adenine dinucleotide, reduced form or nicotinamide adenine dinucleotide phosphate, reduced form, or an analyte (e.g. an enzyme) which produces the reduced forms of nucleotide in biological fluids.
铁离子螯合物适用于测定还原剂或其他可反应生成还原剂的分析物的分析成分、元素和方法。铁离子螯合物被还原成亚铁离子和铁离子配位配体。然后,亚铁离子与合适的亚铁离子配位配体配位,形成有色复合物。特别是,这些组合物和元素可用于检测生物液体中还原型烟酰胺腺嘌呤二核苷酸或还原型烟酰胺腺嘌呤二核苷酸磷酸酯或产生还原型核苷酸的分析物(如酶)。
