β-Glucuronidase/ Arylsulfatase Mix
Genetically enhanced recombinant
β-Glucuronidase-Arylsulfatase dual mix.
Stable for 12 months at 2-8°C.
“The only dual recombinant enzyme reagent - specifically designed for simultaneous hydrolysis of β-glucuronides and sulfo-conjugates from urine in a single reaction. ”
BGS™ is a mix of recombinant β-glucuronidase and aryl-sulfatase enzymes that is capable of deconjugating glucuronide and sulfate conjugates simultaneously under a unique set of incubation conditions.
The enzymatic mix found in BGS™ has been designed such that the β-glucuronidase and Arylsulfatase have overlapping optimum incubation pHs and temperatures. This allows both glucuronide and sulfate conjugates to be hydrolyzed in one efficient step.
Conjugation of xenobiotics represents an important biotransformation reaction in humans and animals. Hydrolysis of glucuronide and sulfate conjugates is especially important in steroid analysis, since many steroids are converted into glucuronidated conjugates, or into the sulfo conjugation via the steroid elimination pathway. Being a high-purity recombinant product, BGS™ avoids conversions and generation of “steroid-like interferences” that frequently occur when using wild-type derived enzymes.
Compared to wild-type species, the stability of the aryl-sulfatase found in BGS™ is substantially improved. This makes it possible to control the proportion of β-glucuronidase to aryl-sulfatase in a predictable, consistent manner, which is simply not feasible when using wild-type enzymes.Specifications
