Product Information

• Product name

  CheKine™ Serum Sodium Colorimetric Assay Kit

• Application notes

  The kit provides a simple method for detecting the sodium concentration in serum samples. In the assay, The sodium and potassium pyroantimonate reagent in the serum form a precipitate in the weakly alkaline solution, and the amount of the precipitate is proportional to the sodium concentration. The sodium content in the serum can be determined according to its turbidity.
