Adenosine Deaminase from bovine spleen 

Protein determined by biuret.

One unit will deaminate 1.0 μmole of adenosine to inosine per min at pH 7.5 at 25 °C.

Suspension in 3.2 M (NH₄)₂SO₄, 0.01 M potassium phosphate, pH 6.0

Adenosine deaminase is a purine catabolic enzyme which catalyzes the deamination of adenosine and 2'-deoxyadenosine with approximately equal specificity. It is ubiquitous in mammalian tissue, and deficiency in adenosine deaminase has been associated with severe combined immunodeficiency disease. The enzyme has been tested as a target for gene therapy treatments of this disease.
