Abstract

Thymus-derived rosette'-forming lymphocytes which have been separated from other SRBC-sensitive cells by means of cotton wool columns were examined for the presence of immunoglobulin. This was carried out by inhibition of rosette formation by anti-immunoglobulin sera. Inhibition was effected by a number of anti-IgM sera shown to contain antibodies with specificities directed towards the hinge' region of the μ chain. No other heavy chain specific antisera were inhibitory. The ratio of rosette inhibition by anti-κ and anti-λ light chain sera varied during the course of the response to SRBC, the latter inhibiting by 89 per cent 3 days post-immunization.

摘要

通过棉纤维柱从其他对绵羊红细胞敏感的细胞中分离出来的胸腺来源的“玫瑰花结”形成淋巴细胞,检测其免疫球蛋白的存在情况。这是通过抗免疫球蛋白血清对玫瑰花结形成的抑制来进行的。抑制作用由多种抗IgM血清实现,这些血清显示含有针对μ链“铰链”区的特异性抗体。没有其他重链特异性抗血清具有抑制作用。在对绵羊红细胞的反应过程中,抗κ和抗λ轻链血清的玫瑰花结抑制率有所不同,后者在免疫后3天的抑制率为89%。
