Sodium Assay Kit (Colorimetric) (ab211096) provides a
convenient two-step method to detect sodium ions (Na+) present in
serum, urine and saliva. In this assay, sodium ions present in the sample are
used by the enzyme β-galactosidase to produce an intermediate product, which
reacts with a developer to generate a color signal that can be detect at OD =
405 nm.
This kit can detect as low as 25 μM sodium in biological
fluids. Endogenous mono-, di-, and trivalent ions, ascorbic acid, creatinine,
glucose, urea, and bilirubin do not interfere with the assay.
This product is manufactured by BioVision, an Abcam company
and was previously called K391 Sodium Assay Kit (Colorimetric). K391-100 is the
same size as the 100 test size of ab211096.
Sodium (Na+) is one of the most important
electrolytes along with chloride, calcium and potassium. Sodium plays vital
roles in the maintenance normal cell functions such as plasma volume, pH
balance or transmission of nerve impulses. Healthy individuals can absorb sodium
ingested in food, and kidneys maintain proper sodium balance by excreting its
excess in urine. Normal Sodium intake has been defined to be between 200-500
mg/day. Hyponatremia (low sodium concentration in blood) can occur in patients
with nephrotic syndrome, excessive vomiting and diarrhea, while Hypernatremia
(high sodium concentration in blood) is developed in patients suffering from
liver diseases, burns, and pregnancy. Traditionally, sodium concentration in
clinical settings is determined by potentiometric, gravimetry, photometry,
titrimetry and flame atomic emission spectroscopy, but these methods require
expensive and complex protocols that need to be performed by trained personnel.
