    ‘these general principles can be applied to all immunoassays’
    [mass noun] ‘the uses of immunoassay in industry’
    • ‘The use of immunoassays that detect antibodies that bind to epitopes on the bacterial surface of the homologous infecting strain is important to detect potentially protective immune responses.’
    • ‘Enzyme immunoassays for detecting chlamydial antigen and direct nucleic acid probe assays are the most widely used tests and can evaluate large numbers of samples.’
    • ‘This has important applications in protein chromatography, immunoassays for medical diagnostic tests, development of biosensors, biotechnology, and biocatalysis.’
    • ‘In medical diagnostics, solid-phase immunoassays are used where immunoglobulins are immobilized on a substrate, which then form sandwichlike complexes with antigens.’
    • ‘Many antibodies used in diagnostic immunoassays are derived from rabbits.’
