Descriptions

Application

?-Glucuronidase/Arylsulfatase has been used extensively in research and analytic laboratories for the simultaneous enzymatic hydrolysis of steroid ?-glucuronides and sulfate esters. The enzyme is used during sample preparation to cleave off glucuronides and sulfate esters prior to GC-MS, HPLC, immunoassays, or other analytical methods, including doping analysis and hydrolysis of steroid conjugates (glucuronides) and sulfate esters in urine and other body fluids.

Components

EC 3.1.6.1 & 3.2.1.31

Features and Benefits

Deconjugate and detect both glucuronides and sulfate esters. Quickly screen for steroids, benzodiazepines, cannabinoids, opioids, and other drugs.

General description

?-Glucuronidase/Arylsulfatase from Helix pomatiais is the most widely used enzyme preparation containing sulfatase activity and has a very broad specificity. It is a crude mixture of enzymes and the preparation does not involve any kind of chromatographic separation. This preparation contains both glucuronidase and sulfatase activity. Enzymatic hydrolysis prior to detection is essential for achieving high sensitivity during analysis. After hydrolysis, the sample may be analyzed by mass spectroscopy, gas chromatography, HPLC, or immunoassays. For doping analysis, the sulfatase activity in addition to the glucuronidase activity is essential for the detection of all drug conjugates present in the sample. ?-Glucuronidase/Arylsulfatase is also used for the enzymatic hydrolysis of glucuronides and sulfate esters in biological fluids and primarily urine.

Other Notes

For life science research only. Not for use in diagnostic procedures.

Physical form

Solution in saline, stabilized

Preparation Note

Working concentration: In many applications the product can be diluted with water immediately before use or employed undiluted.Note: The present β-glucuronidase/arylsulfatase preparation is very concentrated and must be diluted for some applications. Moreover, in the preparation of protoplasts, the precise concentration to use for a given strain of yeast must be found empirically.Storage conditions (working solution): Note: Aliquot portions of the diluted preparation may be stored at -15 to -25 °C; they should not be thawed and refrozen more than a time or two, and storage at the lower temperature does not lengthen their life beyond that of the product kept at 2 to 8 °C.

Principle

Glucuronidation is one of the basic principles of metabolism. Most substances presented to the human body undergo metabolic processing that includes conjugation with glucuronic acid by UDP-glucuronosyltransferases (UGTs). This enzyme catalyzes the transfer of a glucuronyl group to many biological and pharmacologically active endogenous and exogenous molecules. Glucuronide is in general more soluble, less toxic, and more easily excreted by the human body compared to the original molecule.In addition, sulfation of the drug or chemical substance by sulfotransferases in the human body may occur
