It has been found by immunoelectrophoresis, that Group A streptococci release at least 20 distinct extracellular antigens in human tissues, as judged by naturally occurring antibodies present in normal pooled human gamma globulin. Several of these precipitin arcs have been identified with streptococcal antigens previously purified by electrophoresis and chromatography. Human gamma globulin, as well as several rheumatic fever sera, were shown to be remarkably potent in antistreptococcal antibodies, when compared to four horse antibody concentrates obtained by hyperimmunization with several streptococcal filtrates. A Group C streptococcal culture concentrate revealed 8 or 9 antigens for which corresponding antibodies were present in human gamma globulin.
通过免疫电泳发现,根据正常人混合γ球蛋白中天然存在的抗体判断,A组链球菌在人体组织中释放至少20种不同的细胞外抗原。其中几条沉淀弧已被鉴定为先前通过电泳和色谱法纯化的链球菌抗原。与通过用几种链球菌滤液进行超免疫获得的四种马抗体浓缩物相比,人γ球蛋白以及几种风湿热血清显示出具有显著效力的抗链球菌抗体。一种C组链球菌培养浓缩物显示出8或9种抗原,人γ球蛋白中存在针对这些抗原的相应抗体。
