Özet
Phenolphthalein-glucuronide is a commonly used glucuronide conjugate for beta-glucuronidase measurements. The quantity of phenolphthalein liberated by beta-glucuronidase is measured spectrophotometrically. The detection limit of the quantity of phenolphthalein using spectrophotometry is a few mu g. In this study, a new radioanalytical technique for the measurement of beta-glucuronidase was applied which is 10(6) times more sensitive than the spectrophotometric technique. Radioiodinated phenolphthalein-glucuronide and phenyl-N-glucuronide were used in this study in which the beta-glucuronidase levels of some tissue samples were measured.
