CheKine™ Serum Potassium (K+) Colorimetric Assay Kit

Product Information

  • Product name

    CheKine™ Serum Potassium (K+) Colorimetric Assay Kit

  • Application notes

    The kit provides a simple method for detecting Potassium (K+) in serum samples. In the assay, potassium ions (K+) react with sodium tetraphenylborate to form potassium tetraphenylborate which is insoluble in water and the turbidity produced is proportional to the potassium concentration within a certain range. So the serum potassium concentration can be determined by measuring its turbidity.

Additional Information

  • Background

    Potassium (K+) plays an important role in maintaining the body's normal osmotic pressure and acid-base balance. In addition, potassium participates in sugar and protein metabolism, and ensures the normal function of neuromuscular. When serum potassium is higher than 5.5 mmol/L, it is called hyperkalemia. Hyperkalemia can increase nerve and muscle irritability and reduce myocardial irritability which can lead to bradycardia. When serum potassium exceeds 10 mmol/L, ventricular fibrillation may occurs and even the heart stops beating during diastole. When serum potassium is lower than 3.5 mmol/L, it is called hypokalemia. Hypokalemia can cause muscle weakness (even muscle flaccid paralysis) and increase myocardial irritability. In this case, tachycardia and arrhythmia may occur, even the heart stops beating during systole. Therefore, serum potassium is a commonly used biochemical indicator.
