The object of this study was to develop a test that would measure antibodies directed against group B streptococcal types Ia, Ib, Ic, II, and III. The type-specific carbohydrate antigens were purified, labeled with 125I, and used to develop a radioimmunoassay. This procedure should be particularly useful in testing human sera for group B type-specific antibodies, since it requires very small quantities of antigens and measures primary type antigen-antibody interactions.
本研究的目的是开发一种能检测针对B族链球菌Ia、Ib、Ic、II和III型抗体的检测方法。将型特异性碳水化合物抗原纯化,用125I标记,并用于开发放射免疫测定法。该方法在检测人血清中B族型特异性抗体时应特别有用,因为它所需抗原量极少,且能检测主要的型抗原-抗体相互作用。
