本文介绍两种测定甲种胎儿蛋白的新技术——放射火箭电泳自显影术和放射对流免疫电泳。前法系根据标记抗原特异性参入的原理结合放射自显影术和火箭电泳的条件而建立的定量测定法,后法系根据放射免疫的原理结合对流免疫电泳的条件而建立的定量测定法。此二方法具有简便、稳定、特异性强和灵敏度较高以及快速等优点。 This article describes two new techniques for the determination of alpha-fetoprotein: radiometric rocket electrophoresis autoradiography and radio-convection immunoelectrophoresis. The former method is based on the principle of labeling antigen-specific participation combined with the conditions of autoradiography and rocket electrophoresis. The latter method is based on the principle of radioimmunoassay combined with the conditions of countercurrent immunoelectrophoresis to establish a quantitative assay. The two methods have the advantages of simplicity, stability, high specificity, high sensitivity, and high speed.
