An assay for gamma-interferon (IFN gamma) in human lymphocyte culture supernatants, based on reverse passive haemagglutination (RPH) of red cells bearing a monoclonal anti-IFN gamma antibody, was developed and compared with a conventional virus inhibition assay. Test samples comprised supernatants of lymphocytes from patients with Schistosoma mansoni infections, cultured with or without a soluble worm antigen preparation. The two assays gave comparable results, the correlations for individual samples being good. The RPH assay was both specific and sensitive, allowing the detection of IFN gamma at 13 u/ml (1 ng/ml) or less. The advantages of the RPH assay were that it was quick, relatively inexpensive and suitable for testing large numbers of samples. In particular, between-experiment variation was very low, allowing the assay of different samples on different occasions.
基于携带抗γ干扰素单克隆抗体的红细胞反向被动血凝反应(RPH),开发了一种检测人淋巴细胞培养上清液中γ干扰素(IFNγ)的方法,并与传统的病毒抑制试验进行了比较。测试样品包括来自曼氏血吸虫感染患者的淋巴细胞上清液,在有或没有可溶性虫抗原制剂的情况下进行培养。两种检测方法得出的结果相当,单个样品的相关性良好。RPH检测方法具有特异性和敏感性,能够检测出浓度为13 u/ml(1 ng/ml)或更低的IFNγ。RPH检测方法的优点是快速、相对便宜且适合检测大量样品。特别是,实验间的差异非常小,允许在不同时间对不同样品进行检测。
