Other Notes

For life science research only. Not for use in diagnostic procedures.

Physical form

Suspension in 3.2 M ammonium sulfate solution, pH approximately 6

Preparation Note

Activator: PyridoxalphosphateStorage conditions (working solution): The enzyme is stable when dissolved in human serum and frozen in aliquots. For best results, centrifuge the enzyme and decant the supernatant before dissolving the enzyme in human serum to avoid high ammonium sulfate concentrations in the solution.
