A biologically active reagent is prepared by reacting a biologically active substance covalently to a polymeric particle having pendant aldehyde groups. Such groups are provided by a polymerizable monomer represented by the structure:
wherein Ar is arylene, R and R¹ are independently hydrogen, halo or lower alkyl, R² and R³ are independently alkylene of 1 to 4 carbon atoms in the chain, R⁴ is arylene, m is 0 or 1, and n is an integer of 1 to 4. These reagents can be used in a variety of specific binding and affinity purification methods, and in both solution assays and dry analytical elements.
一种生物活性试剂的制备方法是将一种生物活性物质与一种具有醛基团的聚合物粒子共价反应。这些基团由结构如下的可聚合单体提供:
其中 Ar 为芳基,R 和 R¹ 独立地为氢、卤代或低级烷基,R² 和 R³ 独立地为链中含有 1 至 4 个碳原子的亚烷基,R⁴ 为芳基,m 为 0 或 1,n 为 1 至 4 的整数。 这些试剂可用于各种特异性结合和亲和纯化方法,也可用于溶液检测和干分析元素。
