An enzyme-linked immunosorbent assay (ELISA) was developed for human beta-glucuronidase, using a specific polyclonal antibody raised against the purified enzyme. beta-Glucuronidase from human liver consisted of three subunits with molecular mass of 76, 64 and 18 kDa. The assay offered a specific, sensitive and convenient means of measuring immunoreactive beta-glucuronidase in human sera. beta-Glucuronidase activity determined by the conventional method appeared to be extremely low, indicating that in human sera beta-glucuronidase exists in an enzymatically inactive form. The sensitivity of the assay permitted the detection of 1-100 ng of purified beta-glucuronidase. A mean serum level in normal subjects was 108 +/- 25 ng/ml (mean +/- S.D.). A high level of beta-glucuronidase was found in sera of patients with severe hepatocellular necrosis, including liver cirrhosis (152 +/- 130 ng/ml) and chronic active hepatitis (220 +/- 99 ng/ml), whereas no significant increase of the enzyme protein was observed in chronic persistent hepatitis (102 +/- 42 ng/ml). beta-Glucuronidase was also increased in sera of patients with primary hepatoma (156 +/- 125 ng/ml). The immunoreactive beta-glucuronidase determined in this assay was thought to be a supplementary serological indicator for hepatocellular necrosis.
