    • The immunoassay element for quantitatively analyzing an antigen by determining the change in enzymatic activity of an enzyme-labelled antigen or antibody caused by an immunological reaction. The immunoassay element comprises a substrate layer containing a non-diffusible substrate which forms a diffusible material in the presence of the labelling enzyme, and a reagent layer containing a fragmenting enzyme for further fragmenting the diffusible material into a lower molecular weight product. As the non-diffusible substrate, a substrate capable of reacting solely with the labelling enzyme and incapable of reacting the fragmenting enzyme is utilized. When an endo-active glucosidase is used as the labelling enzyme, and an exo-active glucosidase is used the fragmenting enzyme in the reagent layer, the non-diffusible substrate of the substrate layer is preferred to be an endo type selectively reactive substrate, which means a substrate having a reactivity specific to endo-active glucosidase. Highly sensitive assay is realized with high accuracy and high reproducibility and good storage stability.
    • 用于通过确定由免疫反应引起的酶标记的抗原或抗体的酶活性的变化来定量分析抗原的免疫测定元件。 免疫测定元件包括含有在标记酶存在下形成可扩散材料的不扩散基底的底物层和含有用于进一步将可扩散材料分解成较低分子量产物的碎裂酶的试剂层。 作为非扩散性底物,使用能够仅与标记酶反应并且不能使片段化酶反应的底物。 当使用内源活性葡糖苷酶作为标记酶,并且使用外源活性葡糖苷酶时,试剂层中的断裂酶,底物层的非扩散性基质优选为内型选择性反应性底物,其中 是指具有对内源性葡糖苷酶特异性的反应性的底物。 高精度,高重现性和良好的储存稳定性实现了高灵敏度测定。
