The reconstituted urease solution is stable for at least one month when stored at 2–8 °C. Stability may be further extended by freezing. The stability is not effected following multiple freeze–thaw cycles. When reconstituted in 30 mL water, the solution will contain 100 units urease from Jack bean in 27 mM EDTA with 0.1% sodium azide as a preservative.

General description
Urease is a dinickel enzyme that hydrolyses urea into ammonia and carbon dioxide. It is secreted by several bacterial species, invertebrates, fungi, and plants. Detection of urease activity is a potential diagnostic tool for Helicobacter pylori infections and several oral bacterial infections. two Ni2+ ions bridged by a hydroxyl group and a carbamylated lysine.
Application
Urease Buffer Reagent has been used:
- to measure plasma urea N (PUN) by the hypochlorite-phenol nitroprusside method
- in cell viability assay to measure the synthesis of urea in human fetal stem/progenitor cells
- to study the metabolic capacity of rat hepatocytes
Used in conjunction with Phenol Nitroprusside solution (Product Code P 6994) and Alkaline Hydpochlorite solution (Product Code A 1727) for the colorimetric determination of urea.
