Biologically active reagents are prepared from particles of copolymers having highly active succinimide groups. The reagents are prepared by covalently attaching biologically active substances, for example antibodies, to the particles, directly or indirectly through amide groups by displacement of highly active succinimide 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 such as affinity chromatography.
生物活性试剂由具有高活性琥珀酰亚胺基团的共聚物颗粒制备而成。这些试剂的制备方法是通过酰胺基团置换颗粒表面的高活性琥珀酰亚胺基团,将生物活性物质(如抗体)直接或间接地共价连接到颗粒上。这些试剂在分析元件、特定结合配体(如免疫物种)的检测方法、免疫测定以及亲和层析等纯化方法中得到了广泛应用。
