일반 설명

β-Glucuronidase Type H-2 from Helix pomatia is a crude solution of enzymes derived from the digestive juices of the Roman snail. β-glucuronidases derived from mollusks often contain sulfatase activity. Both activities are useful in the hydrolysis of metabolites for toxicology and biomarker analysis. For a broader look at our β-Glucuronidase product line and their uses see our page about Drug Metabolite Analysis

애플리케이션

  • Sample preparation for LC/MS through digestion of glucuronide conjugated compounds for biomarker and toxicology research.
  • Removal of glucuronide conjugates such as for the preparation of Baicalein.­

생화학적/생리학적 작용

Endogenous beta-glucuronidase is a lysosomal enzyme involved in digestion of glucuronide-modified catabolites.
Microbial beta-glucuronidase found in microbiota can cause re-absorption of metabolites by hydrolysis of glucuronide conjugates of xenobiotic and endobiotic metabolites.
Used for the hydrolysis of glucuronide conjugates in urinary metabolite analysis

특징 및 장점

  • pH optima 4.0 - 5.0.
  • Sulfatase pH optima 6.2
  • Low Sulfatase activity (<7,500 units/mL).
  • Ammonium Sulfate suspension.
  • Mollusk-derived beta-glucuronidase.
  • Useful for acidic hydrolysis of glucuronides in low pH samples.

품질

Many β-glucuronidases derived from mollusks also contain sulfatase activity.

결합
