Product Overview :
Potassium Assay is based on a kinetic coupling assay system using potassium dependent pyruvate kinase. Pyruvate generated is converted to lactate accompanying conversion of NADH analog to NAD analog. The corresponding decrease of optical density at 380 nm is proportional to the potassium concentration in the serum.
Description :
Potassium plays an important function in the well-being of healthy individuals. Deviations from normal levels can have severe consequences. It is thus important that researchers identify causes of fluctuations in potassium.
Applications :
The Potassium Kit is for the quantitative determination of potassium in serum. Please read the complete kit insert before performing this assay. The kit is for RESEARCH USE ONLY. It is not intended for use in diagnostic procedures.
Notes :
The Potassium Assay is formulated for use with non-hemolysed serum samples. No special handling or pretreatment is required. Serum samples should be collected such that testing is performed as soon as possible and within 5 days after the specimen collection.
Storage :
Upon receipt of the Potassium Kit, store it at 2-8°C (do not freeze the kit or hold it at temperatures above 25°C).
Warning :
1. Only appropriately-trained personnel should use the kit. Laboratory personnel should wear suitable protective clothing. All chemicals and reagents should be considered potentially hazardous. Avoid ingestion and contact with skin and eyes.
2. Some assay components contain human sourced materials. Accordingly, all assay components should be handled as if potentially infectious using safe laboratory procedures.
3. Reagents contain lithium azide, which may react with lead and copper plumbing to form highly explosive compounds. On disposal, flush with a large volume of water to prevent buildup.
4. Do not use the reagents after the expiration date.
