Application

New Technical Article Comparing Performance of Different EnzymesLearn 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

Biochem/physiol Actions

Used for the hydrolysis of glucuronide conjugates in urinary metabolite analysis

Packaging

2 mL in glass bottle

Physical form

Aqueous solution in ~1.0 M ammonium sulfate with 3 mM sodium azide as preservative.

Quality

Many β-glucuronidases derived from mollusks also contain sulfatase activity.

Unit Definition

One Sigma or modified Fishman unit will liberate 1.0 µg of phenolphthalein from phenolphthalein glucuronide per hr at 37 °C at pH 5.0 (30 min assay).

Sulfatase Unit Definition: One unit of sulfatase will hydrolyze 1.0 µmole p-nitrocatechol sulfate per hr at pH 5.0 at 37 °C.
