Description

General description

Sodium (Na) is one of the most important electrolytes along with chloride, calcium and potassium. Na plays vital roles in the maintenance of plasma volume, pH balance, transmission of nerve impulses, and normal cell functions. Healthy individuals can absorb sodium ingested in food, and kidneys maintain proper sodium balance by excreting its excess in urine. Sodium sources include table salt, milk, meat, shellfish, bread, snack food, etc. Increased dietary sodium intake increases the risk of susceptibility to cardiovascular disease (CVD), most importantly with elevated blood pressure (BP).

Suitability

Suitable for the determination of sodium concentration in a variety of samples.

Principle

This sodium assay kit offers a simple, two-step colorimetric assay that is based on the requirement of sodium ion as a cofactor for the enzymatic activity of b-galactosidase (βG). Endogenous mono, di, and trivalent ions, ascorbic acid, creatinine, glucose, urea and bilirubin do not interfere with the assay. The kit can detect sodium ion concentrations as low as 25mM in a variety of samples.
