Aplicação

Novo artigo técnico comparando o desempenho de diferentes enzimas
Saiba mais sobre os dados de aplicação recentes, gerados pelo departamento de pesquisa e desenvolvimento da Sigma, para otimizar a hidrólise para classes diferentes de medicamentos, usando enzimas de diferentes fontes e o uso de uma enzima purificada por cromatografia para reduzir o efeito da atividade da esterase que resulta em conversão de 6-MAM em morfina
A enzima de Patella vulgata é considerada mais eficaz na hidrólise de glicuronídeos opioides que as enzimas de Helix pomatia, fígado bovino e E. coli

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.

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.
