ADA ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Adenosine Deaminase (ADA) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Adenosine Deaminase (ADA) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

Catalyzes the hydrolytic deamination of adenosine and 2-deoxyadenosine (PubMed:8452534, PubMed:16670267) . Plays an important role in purine metabolism and in adenosine homeostasis. Modulates signaling by extracellular adenosine, and so contributes indirectly to cellular signaling events. Acts as a positive regulator of T-cell coactivation, by binding DPP4 (PubMed:20959412) . Its interaction with DPP4 regulates lymphocyte-epithelial cell adhesion (PubMed:11772392) . Enhances dendritic cell immunogenicity by affecting dendritic cell costimulatory molecule expression and cytokines and chemokines secretion (By similarity) . Enhances CD4+ T-cell differentiation and proliferation (PubMed:20959412) . Acts as a positive modulator of adenosine receptors ADORA1 and ADORA2A, by enhancing their ligand affinity via conformational change (PubMed:23193172) . Stimulates plasminogen activation (PubMed:15016824) . Plays a role in male fertility (PubMed:21919946, PubMed:26166670) . Plays a protective role in early postimplantation embryonic development (By similarity) .

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Adenosine Deaminase (ADA) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Adenosine Deaminase (ADA) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Adenosine Deaminase (ADA), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Adenosine Deaminase (ADA) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
