A simplified, indirect radioimmunoassay is described for Escherichia coli, vaccinia virus, and herpesvirus. The antigens were affixed to glass cover slips; thus both the primary and secondary reactions take place on the cover slips, and the unbound antiserum is easily separated from the bound antiserum by rinsing. Rabbit or human immune sera were reacted with the antigens, and the primary immune complex was quantitated by a secondary reaction with (125)I-indicator globulin (anti-rabbit or anti-human). A direct relationship between the antiserum concentration and the (125)I absorption was established. Variations in titers were detectable, and the titers were comparable to complement fixation titers. Homologous and heterologous reactions were distinguishable. The method affords an objective, quantitative, and qualitative evaluation of antibody, and results are reproducible.
本文描述了一种用于检测大肠杆菌、痘苗病毒和疱疹病毒的简化间接放射免疫测定法。抗原固定在玻璃盖玻片上;因此,一级反应和二级反应均在盖玻片上进行,通过冲洗可轻松将未结合的抗血清与结合的抗血清分离。兔或人免疫血清与抗原反应,通过与(125)I标记球蛋白(抗兔或抗人)的二级反应对一级免疫复合物进行定量。确定了抗血清浓度与(125)I吸收之间的直接关系。可检测到滴度的变化,且这些滴度与补体结合滴度相当。同源反应和异源反应可区分。该方法可对抗体进行客观、定量和定性评估,结果具有可重复性。
