Abstract
Rapid, sensitive and accurate immunoassays for biologically active natural or recombinant human interferon-gamma (huIFN-gamma) based upon monoclonal antibodies which react specifically with epitopes of the biologically active form of huIFN-gamma are disclosed. The immunoassays include sandwich immunoradiometric assay of the forward, reverse or simultaneous type and competitive binding assay such as radioimmunoassay. The assays are also useful for the detection of macrophage activation factor now believed to be identical to huIFN-gamma. In addition, methods of purification of huIFN-gamma employing the monoclonal antibodies are described.
