The Potassium BioAssay™ Kit is a turbidimetric assay for the detections of potassium in serum, plasma, milk, tissue and cells.||Test Principle:|In alkaline media, potassium ions in serum samples treated by protein precipitates can react with NA-TPB to generate turbid and stable suspensions. The turbidity is proportional to the potassium ion concentration in the sample.||Detection Range: |0.01-0.8mmol/L||Sensitivity:|0.002mmol/L||Precision: |Intra-Assay CV: <4%|Inter-Assay CV: <6%||Kit Components:|405816A: Microtiter wells, 1x96 wells|405816B: Precipitant A, 1x20ml|405816C: Precipitant B, 2x1.25ml|405816D: Chromogenic Agent A, 2x12.5ml|405816E: Chromogenic Agent B, 2x1vial|405816F: Standard, 1mmol/L, 2x1.25ml||Storage and Stability:|Store all components at 4°C.
