Application

New Technical Article Comparing Performance of Different Enzymes
Learn more about recent application data generated by Sigma R&D to optimize hydrolysis for different drug classes using enzymes from different sources and the use of a chromatographicaly purified enzyme to reduce the effect of esterase activity resulting in conversion of 6-MAM to Morphine
The enzyme from patella vulgata is reported to be more effective in hydrolyzing opioid-glucuronides than the Helix pomatia, bovine liver and E. coli enzymes

beta-Glucuronidase from Patella vulgata, Helix aspersa, Helix pomatia, and bovine liver were evaluated for usefulness in routine hydrolysis of drug-glucuronic acid conjugates from equine urine samples. Factors affecting the reaction rate (enzyme concentration, ligand concentration, temperature, and pH) were optimized.

Evaluation of Different Enzymes on Hydrolysis Efficiencies of Glucuronide Drug Metabolites in Urine

β-glucuronidase (GUS) enzymes are utilized to hydrolyze glucuronide (gluc) drug metabolites to the parent drug, facilitating analysis by LC-MS/MS.

Protocols

LC/MS (TOF) Analysis of Drugs and Their Glucuronide Metabolites in Urine on Titan™ C18 after Solid Phase Extraction (SPE) using Supel™-Select SCX, β-Glucuronidase Enzyme Digestion

-THC solution, 1.0 mg/mL in methanol, ampule of 1 mL, certified reference material

Using UHPLC/MS (TOF) for Detection of Drugs and Metabolites in Urine Following Optimized Enzymatic Hydrolysis Conditions

To optimize hydrolysis using β-glucuronidase, factors such as incubation time, temperature, hydrolysis pH, enzyme source, and enzyme concentration must be evaluated for each glucuronide metabolite to be analyzed.
