Sensitive enzyme immunoassay system for measurement of β-thromboglobulin (β-TG) in plasma was prepared with purified antibody to β-TG and β-D-galactosidase from Escherichia coli as labeled substance. The antibodies were purified with an immunoaffinity chromatography form the antiserum, which had been produced in rabbits by injecting purified β-TG. The assay system consisted of the polystyrene bead with immobilized antibody F (ab')2 fragments and the antibody Fab' fragments labeled with β-D-galactosidase. The assay was highly sensitive with β-TG measurable at levels as low as 10 pg/assay tube. β-TG levels in plasma was measured with 2.5 μl samples. Under the conditions, coefficient of variation for within and between run was less than 8% and the results obtained with the enzyme immunoassay correlated well with those with a radioimmunoassay. The plasma β-TG levels in healthy subjects determined with the present assay system were 38.4±6.2 ng/ml and the levels were markedly high in patients with myeloproliferative syndrome and in patients with DIC.
