We have found that the sensitivity of the IPA assay is increased by incubating the cells with a rabbit anti-immunoglobulin serum before the incubation with IPA, to allow detection of antibodies that do not bind IPA directly. A further modification is the use of autoradiography to detect positive reactions; for screening large numbers of samples this is simpler and cheaper than scintillation counting. The indirect IPA assay described here uses commercially available reagents to detect antibodies of most species irrespective of their immunoglobulin class or subclass, can be applied to both adherent and non-adherent cells, and is sensitive and accurate. We have used the indirect IPA assay in the isolation and cloning of hybridomas producing antibodies to cell surface antigens of human melanomas (Yeh et al., 1979) and mouse sarcomas (J. Brown, manuscript in preparation).",
