Invitrogen™ Potassium (K) Turbidimetric Assay Kit
The Potassium (K) Turbidimetric Assay Kit is a highly reliable and sensitive assay designed for the quantitative measurement of potassium content in serum, plasma, milk, tissue, cells, and other sample types.
Potassium is an essential ion that plays a crucial role in various physiological processes, including muscle and nerve function, fluid balance, and cardiovascular health.
Potassium deficiency and excess can each result in different signs and symptoms, including abnormal heart rhythm and various electrocardiographic abnormalities.
Assay Principle
Under alkaline conditions, potassium ions in the sample react with sodium tetraphenylborate to form potassium tetraphenylborate, a turbid white solution with little solubility.
The turbidity is proportional to the potassium ion concentration, which can be calculated indirectly by measuring the OD value at 450 nm.
Key Features
- Simple and fast protocol—user-friendly, requiring minimal hands-on time and providing rapid results within a short incubation period
- Broad range of kits—covering key analytes and targets within important metabolic pathways
- Consistent—strict quality control criteria to ensure reproducible and reliable results
