Aspirin challenge of aspirin-intolerant asthma (AIA) patients causes a significant increase in leukotriene E4 (LTE4) concentration in urine. However, knowledge on leukotriene B4 (LTB4) generation in patients with AIA is insufficient. Recent research has demonstrated that exogenously administered LTB4 is

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.

Probiotics and Human Health

Probiotics exhibit an inhibitory effect on pathogens, help prevent chronic intestinal inflammatory diseases or atopic syndromes, and support the immune system.

实验方案

Enzymatic Assay of β-Glucuronidase (EC 3.2.1.31) from E. coli

Objective: To standardize a procedure for the enzymatic assay of β-Glucuronidase.

使用UHPLC/MS（TOF）检测不同酶水解条件处理的尿液中药物和代谢物

为了使用β-葡糖醛酸酶优化水解，必须对每种待分析的葡糖苷酸代谢物进行某些因素的评估，例如孵育时间、温度、水解pH、酶源和酶浓度。

UHPLC/MS for Drug Detection in Urine

Optimize β-glucuronidase hydrolysis for glucuronide metabolite analysis considering factors like time, temperature, pH, and enzyme concentration.
