- Abstract
An assay for gamma-interferon (IFNγ) in human lymphocyte culture supernatants, based on reverse passive haemagglutination (RPH) of red cells bearing a monoclonal anti-IFNγ 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 IFNγ 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.
