报道了以试管为固相载体，通过共价键的联结把两株癌胚抗原单抗结合到试管壁上，并标记另一株单抗，建立了癌胚抗原试管固相免疫放射分析法．该法具有较高的特异性和灵敏度，操作简便，重复性好，与液相放免法对照测定样品，两者结果密切相关． Reported that the test tube as the solid phase carrier, the covalent bond of the two anti-carcinoembryonic antigen monoclonal antibody bound to the tube wall, and labeled another monoclonal antibody, established a carcinoembryonic antigen tube solid phase immuno-radioactive assay . The method has high specificity and sensitivity, simple operation, good repeatability, and liquid phase radioimmunoassay determination of the sample, the two are closely related results.
