A simple method for detection of IgG rheumatoid factor (RF) in sera and joint fluid is described. The technique is based on the action of 0.1 M 2-mercaptoethanol mixed directly with the material. After 2 h of incubation determinations of human anti-IgG were performed by latex agglutination test. Comparison with data obtained by using the conventional method, sequential 24 h treatment with 0.1 M 2-mercaptoethanol and 0.01 M iodoacetamide, shows similar results for both methods. A correlation was observed between the presence of IgGRF in synovial fluid and a severe clinical course with invalidating forms in patients suffering rheumatoid arthritis.
本文描述了一种检测血清和关节液中IgG类风湿因子(RF)的简单方法。该技术基于将0.1M 2-巯基乙醇直接与样本混合的作用。孵育2小时后,通过乳胶凝集试验测定人抗IgG。与使用传统方法(用0.1M 2-巯基乙醇和0.01M碘乙酰胺连续处理24小时)获得的数据进行比较,两种方法结果相似。在类风湿关节炎患者中,观察到关节液中IgG RF的存在与严重临床病程及致残形式之间存在相关性。
