Increased concentrations of phosphorus are found in renal failure, hypoparathyroidism and upon loss of calcium phosphate from bone tissue and cells. Decreased phosphorus levels are observed in malabsorption, hyperparathyroidism and vitamin D deficiency. The enzymatic-colorimetric assay measures phosphorus in serum, plasma and urine. n Linearity: up to 20 mg/dL n Reconstituted reagent stability: 15 days when stored at 2-8C n Includes standard Technical information: Inorganic phosphates, in the presence of purine nucleoside phosphorylase (PNP), react with inosine forming ribose-1-phosphate and hypoxantine. The latter, in the presence of xanthine oxidase (XOD), is converted into xanthine and then into uric acid with formation of equivalent amount of hydrogen peroxide. In the presence of peroxidase (POD), hydrogen peroxide reacts with 4-aminoantipyrine and 2-hydroxy-3,5-dichloro benzene sulphonic acid (DHBS) forming a red quinone compound, the colour intensity of which is proportional to the concentration of inorganic phosphate ions present in the sample. Phosphorus Catalogue Number 17182 Phosphorus Assay 5x10ml 16150 Clin Chem Control 1 6x5ml 16250 Clin Chem Control 2 6x5ml Sentinel Potassium For quantification of potassium in serum. Too much potassium in the blood, hyperkalaemia, is most commonly caused by kidney disease. Certain drugs can also decrease the amount of potassium excreted. Hypokalaemia, low potassium, can also be induced by drugs such as diuretics or by severe diarrhoea and vomiting. n Photometric method n Single, ready-to-use reagent n Linearity up to 8.0 mmol/L Technical information: Potassium is determined spectrophotometrically through a kinetic coupling assay system using potassium dependant pyruvate kinase. The substrate reagent is converted by the pyruvate kinase in the presence of potassium to give pyruvate which is in turn converted to lactate with concomitant conversion of NADH to NAD. The corresponding decrease of optiaclk density at 380nm is proportional to the postassium concentration in the sample. Potassium Catalogue Number Description Pack Size Description Pack Size 910110 Potassium Photometric Reagent 4x10ml;1x10ml 910180SV Potassium Standards Set 2x3ml 910190SV Potassium Control Set 2x3ml Dialab Rheumatoid Factor - Turbidimetric For the determination of rheumatoid factor (RF) activity in serum. RF is elevated in the serum of rheumatoid arthritis patients and is a specific biomarker for this disease. n Dual liquid-stable reagent n Measurable range: 10-500 U/ml n Open-vial stability: until expiry date when stored at 2-10C Rheumatoid Factor Catalogue Number Description Pack Size 419-70757 RF-HA II Turbidimetric Assay Antibody: 2x20ml Buffer: 2x67ml 419-77902 Rheumatoid Calibrator 5x1ml Wako Chemicals Rheumatoid Factor - Latex Turbidimetric Immunoassay Latex immunoassay for determination of Rhematoid Factor (RF) in serum and plasma. RF is an autoantibody seen in high concentrations in the serum or plasma of patients with Rheumatoid arthritis but is also of assistance in the diagnosis and monitoring of systemic lupus erythematosus, chronic hepatopathy and other diseases. n Ready to use reagents n Open-vial stability: 60 days n Linearity: up to 120IU/ml Technical information: The assay uses and antigen-antibody reaction which occurs between denatured human IgG and Rheumatoid Factor in the sample. The denatured IgG in the reagent is pre-adsorbed onto latex particles and therefore the antigen-antibody reaction results in agglutination which produces a change in absorbance that is proportional to the quantity of RF in the sample.
