sur les données d′applications récentes générées par la R&D Sigma pour optimiser l′hydrolyse de différentes classes de médicaments à l′aide d′enzymes provenant de diverses sources et sur l′utilisation d′une enzyme purifiée par chromatographie pour réduire l′effet de l′activité estérase entraînant la conversion de 6-MAM en morphine
Efficace dans l′hydrolyse des glucuronides stéroïdes.
Sert à hydrolyser les conjugués glucuronides lors de l′analyse de métabolites urinaires
β-Glucuronidase was used in the study of Cer-β-glucuronide synthesis and evaluation of β-glucuronidase(s) from Escherichia coli or intestinal segments to release the head group.

Physical form

β-glucuronidase is used as a reporter gene in GUS assays to monitor gene expression.
Highly purified solution in 50% glycerol

Other Notes

One Sigma or modified Fishman unit will liberate 1.0 μg of phenolphthalein from phenolphthalein glucuronide per hr at 37 °C at the pH 6.8 (30 min assay).
