Abstract

Using a modified solid phase radioimmunoassay (RIA), sera from 11 patients with systemic lupus erythematosus (SLE) that had high DNA binding activities were analysed for their ability to cross-react with phospholipids. Polyspecific anti-DNA antibodies that reacted with both ssDNA and dsDNA had the ability to cross-react with phospholipids, especially cardiolipin. The relationship between biological false-positive serological tests for syphilis (BFP-STS) and the magnitude of serum anti-DNA antibody levels is also discussed.

摘要

采用改良的固相放射免疫测定法(RIA),对11例具有高DNA结合活性的系统性红斑狼疮(SLE)患者的血清进行分析,以检测其与磷脂发生交叉反应的能力。能与单链DNA和双链DNA发生反应的多特异性抗DNA抗体具有与磷脂,尤其是心磷脂发生交叉反应的能力。文中还讨论了梅毒生物学假阳性血清试验(BFP-STS)与血清抗DNA抗体水平高低之间的关系。
