beta-Glucuronidase from Helix pomatia (C15-1289-944)

General description

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

Application

• 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.­

Biochem/physiol Actions

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

Features and Benefits

• 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.

Quality

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

Linkage

Similar to G0876, but produced by Sigma.

Unit Definition
