General description

Urease is a 545 kDa protein critical for the hydrolysis of urea to carbon dioxide and ammonia.
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.
