Adenosine Deaminase Kit（Enzymatic Colorimetric Method)
Adenosine Deaminase Kit（Enzymatic Colorimetric Method）
In vitro test for the quantitative determination of ADA activity in serum on photometric systems.
ADA ia an enzyme catalyzing the deamination reaction from adenosine to inosine. The enzyme is widely distributed in human tissues, especially high in T lymphocytes and red cell. Elevated serum ADA activity has been observed in patients with acute hepatitis , hepatocirrhosis ,hepatoma. tuberculous effusions. and typhoid. Determination of ADA activity in patient serum may add unique values to be useful in the diagnostics of liver diseases in combination with ALT or GGT tests. ADA assey may also be usefui in the diagnostics of tuberculous pleuritis. Lower lever serum ADA activity has been observed in patients with virosis meningitis, serious immunodeficiency.
This Benzoquinone is detected as an absorbance change (546 nm), with the increase of the absorbency being proportional to the quantity of ADA in the sample
