More on the suitability of this product for hydrolysis of different drug-glucuronide substrates is available at this page.

特点和优势

Formulated with a higher enzyme concentration for applications requiring ultra-fast hydrolysis rates. Recombinantly expressed and purified to eliminate MAM esterase activity (6-Monoacetylmorphine→morphine). Representative analysis at high enzyme titer (50 un/μL β-glucuronidase) was less than 1% conversion of 6-MAM to morphine after 4 hours at 60 °C.

单位定义

One Sigma or modified Fishman unit will liberate 1.0 μg of phenolphthalein from phenolphthalein glucuronide per hr at 37 °C at pH 3.8 (30 min assay).

外形

Supplied as a solution in 100mM potassium acetate pH 5.2. It is free of detergents, carbohydrates or any other components that may interfere with sample preparation and analysis.
