将体外翻译产物的免疫沉淀物经SDS-聚丙烯酰胺电泳，得到相当于人血清白蛋白的同位素标记的电泳区带。

When the immunoprecipitate was subjected to SDS agarose gel electrophoresis, 3 radioactive bands were obtained, one of which corresponded to pure human albumin in its position.

方法：以同位素标记的单克隆抗体和微球的结合率为指标。用均匀设计法研究影响免疫磁性微球构建的因素。

Methods: What determines the binding percent of monoclonal antibodies to make magnetic beads is studied by uniform design methods, isotope marked antibody's binding percent as the criteria.
