A dry analytical element can be used to sensitively and rapidly detect a wide variety of specific binding ligands in either a competitive binding or sandwich assay format. The assays are carried out using a peroxidase-labeled immunoreactant. The peroxidase label is stabilized with a 4-hydroxy or 4-alkoxyarylacetamide which is located in one or more zones of the element. Not only is the label stabilized with the stabilizer, but the assay is more sensitive.
干式分析元件可用于以竞争性结合或夹心检测的形式灵敏、快速地检测各种特异性结合配体。检测使用过氧化物酶标记的免疫反应物。过氧化物酶标签用 4-羟基或 4-烷氧基芳基乙酰胺稳定,这种乙酰胺位于元件的一个或多个区域。使用稳定剂不仅可以稳定标签,还能提高检测灵敏度。
