Általános leírás

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.

Alkalmazás

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.

The broad distribution of ureases in leguminous seeds, as well as the accumulation pattern of the protein during seed maturation, are suggestive of an important physiological role for this enzyme. Since the isolation and characterization of jack bean urease by

Organs from non-heart-beating donors are attractive for use in cell therapy. Understanding the nature of molecular perturbations following reperfusion/reoxygenation will be highly significant for non-heart-beating donor cells. We studied non-heart-beating donor rats for global gene expression with Affymetrix microarrays, hepatic
