Adenosine Deaminase (ADA, E.C. is an enzyme that catalyzes the conversion of adenosine and 2’-deoxyadenosine to inosine and 2’-deoxyinosine. Adenosine is a metabolite that plays important roles in determining cell proliferation, cell cycle progression, and immunosuppressive activation. Although multiple pathways exist for the production of adenosine, its deamination is irreversible, and becomes a critical point in purine metabolite signaling. Both adenosine and inosine bind the adenosine A2A receptor yet can trigger different downstream signaling. Excess adenosine in penile tissue contributes to the disorder called priapism, and impaired adenosine signaling is associated with erectile dysfunction. For this reason, substantial work has gone into identification of inhibitors that would be of clinical relevance. The major isoform of adenosine deaminase, ADA1, is widely expressed in most cells in humans, particularly in lymphocytes and macrophages. ADA1 is present in the cytosol, nucleus and found associated with dipeptidyl peptidase-4 on the cell membrane while ADA2 was first found in the spleen but is predominantly found in the plasma and serum. Adenosine signaling is part of the immune response, and has been shown to reduce T-cell activation. Adenosine Deaminase activity is thus a marker for T-lymphocyte proliferation. BioVision’s Adenosine Deaminase (ADA1) Inhibitor Screening Kit includes the larger 41 kDa form, human ADA1. In BioVision’s ADA inhibitor screening kit, adenosine is deaminated by ADA1 forming inosine. This intermediate is converted to uric acid by a series of enzymatic reactions. The formed uric acid can be measured in the supplied U.V. transparent plate at OD 293 nm. A highly specific ADA1 inhibitor is included as a positive control for inhibition. The kit provides a rapid, simple, sensitive, and reliable test, suitable for high-throughput screening of ADA1 inhibitors.
