Product Features
The assay is linear from 0-200 U/L (r2 >0.99) and has precisions of Intra assay %CV < 4.5% and Inter assay %CV < 6.0%.The assay is ready-to-use for both manual method and automated chemistry analyzers (Kinetic). The assay is specific for ADA and has no detectable reaction with other nucleosides and is not affected by serum bilirubin up to 20 mg/dL, hemoglobin up to 200 mg/dL, triglycerides up to 750 mg/dL, or ascorbic acid up to 4 mg/dL. The assay is based on H2O2 detection, which is more sensitive and reliable than the method detecting ammonia production and is stable for 12 months when stored @ 2°-8°C shielded from light.


Assay Principle
The ADA assay is based on the enzymatic deamination of adenosine to inosine, which is converted to hypoxanthine by purine nucleoside phosphorylase (PNP). Hypoxanthine is then converted to uric acid and hydrogen peroxide (H2O2) by xanthine oxidase (XOD). H2O2 is then quantified by a Trinder reaction.


Intended use
The Adenosine Deaminase (ADA) assay kit is for determination of ADA activity in human serum, plasma, pleural fluid and cerebrospinal fluid (C.S.F. samples). For investigational use or export only.
