Biologically active reagents are prepared from particles of copolymers having highly reactive carboxy or equivalent groups. The reagents are prepared by covalently attaching biologically active substances, for example antibodies, to the particles, directly or indirectly through highly reactive carboxy groups on the particle surface. These reagents are used to advantage in analytical elements, methods for the detection of specific binding ligands (such as immunological species) and immunoassays, and in purification methods as affinity chromatography reagents.
生物活性试剂由具有高活性羧基或等效基团的共聚物颗粒制备而成。制备试剂的方法是将
生物活性物质(如
抗体)直接或间接地通过颗粒表面的高活性羧基共价连接到颗粒上。这些试剂可用于分析元件、检测特定结合
配体(如免疫物种)的方法和免疫测定,也可作为亲和层析试剂用于纯化方法。
