A homogeneous specific binding assay device, a method for its preparation, and a method for its use in determining a ligand, such as antigen, hapten, or antibody, in, or the ligand binding capacity of, a liquid sample. The test device comprises a solid carrier member, such as a fibrous web matrix, e.g., paper, or a polymeric film or gel, incorporated with reagents for a homogeneous specific binding assay system which produces a detectable response, usually an electromagnetic radiation signal, that is a function of the presence or amount of the ligand in or the ligand binding capacity of the sample. Useful homogeneous specific binding assay systems include those involving enzyme substrate labels, enzyme prosthetic group labels, and enzyme labels. The detectable response preferably is a luminescent, fluorescent, spectrophotometric. or colorimetric response, which is measurable by visual observation or instrument means.
一种均相特异性结合测定装置、一种制备方法和一种用于测定液体样品中的配体(如抗原、合体或抗体)或配体结合能力的方法。测试装置包括一个固体载体部件,如纤维网基质(如纸张)或聚合物薄膜或凝胶,其中含有用于均相特异性结合检测系统的试剂,该系统可产生可检测的响应,通常是电磁辐射信号,该响应是样品中配体的存在或数量或配体结合能力的函数。有用的均相特异性结合检测系统包括酶底物标签、酶假基标签和酶标签。可检测的反应最好是发光、荧光、分光光度或比色反应,可通过肉眼观察或仪器测量。
