Enzymes for Research, Diagnostic and Industrial Use

β-Glucuronidase from E. coli, Recombinant

Cat No.
NATE-1092
Description
β-glucuronidase catalyzes the breakdown of complex carbohydrates. In humans it converts conjugated bilirubin into the unconjugated form, making bilirubin suitable for reabsorption.
Abbr
GUSB, Recombinant (E. coli)
Alias
GUSB
Source
E. coli
Applications
High purity recombinant beta-Glucuronidase (Escherichia coli) for use in research, biochemical enzyme assays and in vitro diagnostic analysis.
Form
Supplied in solution (Tris.HCl / NaCl / EDTA).
