A buffered aqueous composition is useful simultaneously as a wash solution and a dye-providing composition in specific binding assays involving enzyme-labeled specific binding reagents. The wash composition includes a dye-providing composition, a buffer and an organic solvent having a certain molecular weight and water-solubility. Another useful composition includes a particulate substrate having avidin attached thereto, and a peroxidase reducing agent. Either composition can be provided in a diagnostic test kit, and can be used to detect a
specific binding ligand in assays.
在涉及酶标记的特异性结合试剂的特异性结合检测中,缓冲
水溶液组合物可同时用作洗涤液和供染组合物。洗涤组合物包括
染料提供组合物、缓冲液和具有一定分子量和
水溶性的有机溶剂。另一种有用的组合物包括附有阿维丁的颗粒基质和
过氧化物酶还原剂。这两种组合物都可以在诊断检测试剂盒中提供,并可用于在检测中检测特定的结合
