Descrizione generale

Urease is a 545 kDa protein critical for the hydrolysis of urea to carbon dioxide and ammonia. [1]
Urease is a dinickel enzyme that hydrolyses urea into ammonia and carbon dioxide.[2][3] It is secreted by several bacterial species, invertebrates, fungi, and plants.[3] Detection of urease activity is a potential diagnostic tool for Helicobacter pylori infections and several oral bacterial infections.[2] two Ni2+ ions bridged by a hydroxyl group and a carbamylated lysine.[3]

Applicazioni

Urease Buffer Reagent has been used:
  • to measure plasma urea N (PUN) by the hypochlorite-phenol nitroprusside method[4]
  • in cell viability assay to measure the synthesis of urea in human fetal stem/progenitor cells[5]
  • to study the metabolic capacity of rat hepatocytes[6]

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 nickel-dependent urease enzyme is responsible for the hydrolysis of urea to ammonia and carbon dioxide. A number of bacteria produce urease (ureolytic bacteria) and are associated with various infectious diseases and ammonia emissions from agriculture. We report the first

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
