β-Glucuronidase is routinely used to hydrolyze glucuronide-conjugates of drug metabolites in order to optimize sample preparation prior to LC-MS, GC and ELISA analysis.
LC-MS analysis of codeine-glucuronide enzymatic hydrolysis with six different Sigma-produced β-glucuronidase preparations. The limpet-derived enzyme G8132 performed best with this substrate, with reaction completion within 3–4 hours at 60 °C at 1 unit per mL. Comparative data above was performed at 60 °C at 10 unit per mL.
LC-MS analysis of hydromorphone-glucuronide enzymatic hydrolysis with six different Sigma-produced β-glucuronidase preparations. Molluscan enzymes performed similarly. The reaction was complete within 3–4 hours at 60 °C at 1 unit per mL. The E. coli enzymes exhibited low specificity for this substrate.
