title: A sensitive reverse passive haemagglutination immunoassay for hepatic caeruloplasmin.
abstract: A reverse passive haemagglutination assay for the measurement of caeruloplasmin in homogenates and organelle fractions prepared from needle biopsies of human liver tissue is described. Use of serial dilutions over a narrow range of concentrations permits accurate quantitation of caeruloplasmin down to 10 ng/ml, sufficient to detect the protein in needle biopsies with as little as 5 mg wet weight of tissue. Applied to the measurement of caeruloplasmin in human sera, the assay gives values which correlate well with those obtained by the standard radial immunodiffusion technique.
