General description

Sodium carbonate (Na2CO3) is an inorganic compound also known as soda ash. It is used in flue gas desulfurization, and in detergent formulations. It is a stronger alkali used as a softening agent in laundry detergents.

Application

Sodium carbonate can be used:
  • A sintering aid with the ZnO (zinc oxide) for the preparation of BaCe0.5Zr0.3Y0.2O3−δ based composite electrolyte material by solid-state reaction.
  • A co-precipitating agent for the synthesis of stable iron oxide nanoparticles from a stoichiometric combination of Fe(II) and Fe(III) salts.
  • A catalyst for the etherification of glycerol to polyglycerols.

Biochem/physiol Actions

Componente amortiguador, puede utilizarse para eliminar las proteínas periféricas de membrana.

Universal Protease Activity Assay: Casein as a Substrate

Proteases break peptide bonds. In the lab, it is often necessary to measure and/or compare the activity of proteases. Sigma's non-specific protease activity assay may be used as a standardized procedure to determine the activity of proteases, which is what we do during our quality control procedures.

Universal Protease Activity Assay using Casein as a Substrate

Measure and compare the activity of proteases with this non-specific protease activity assay using casein. Use this assay as a standardized procedure to determine the activity of proteases for quality control.
