  • Beta-Glucuronidase Powder

    Beta-Glucuronidase Powder (β-Glucuronidase), which is derived from Abalone (Molluskan Source), is used by toxicologists to detect a variety of drug metabolites (ie. opiods, steroids, cannabinoids, benzodiazipines, etc.) in urine, plasma, and other biological fluids. Beta-Glucuronidase functions by enzymatically hydrolyzing glucoronides prior to analysis by LCMS, immunoassay, mass spectrometry, GCMS or other methods. CovaChem's Beta-Glucuronidase is prepared to provide exceptionally high activity to allow complete hydrolysis of glucuronide conjugates.

    CovaChem's Beta-Glucuronidase lyophilized powder is highly active and easily dissolves in water. This enzyme is also available as a (β-Glucuronidase solution).
