Studies on human liver bilirubin-UDP-glycosyl transferase. I. Assay methods for bilirubin-UDP-glucuronyl and -xylosyl transferases of human liver specimen.
Micromethods for estimation of bilirubin uridine diphosphate-glucuronyl and -xylosyl transferases in liver are described. With these methods, a liver specimen as small as 10 mg is sufficient for assay of either enzyme activity and 15 mg is sufficient for assay of both enzymes. Normal values for livers with minimal elevation of SGOT and minimal histological change were 0.260-0.400 U/g protein for glucuronyl transferase and 0.142-0.302 U/g protein for xylosyl transferase.
