Anti-ADA2 antibodies are used in the immunodetection of the protein adenosine deaminase 2. In humans, the canonical protein has a reported length of 511 amino acid residues and a mass of 58.9 kDa. It has been described to be a secreted protein. Up to 2 different isoforms have been reported for this protein. It is notably expressed in blood plasma. A member of the Adenosine and AMP deaminases protein family, ADA2 is reported to be an adenosine deaminase that may contribute to the degradation of extracellular adenosine, a signaling molecule that controls a variety of cellular responses. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include CECR1, IDGFL, PAN, SNEDS, VAIHS, adenosine deaminase CECR1, cat eye syndrome chromosome region, candidate 1, and ADGF. ADA2 gene orthologs have been reported in the bovine, frog, zebrafish, chimpanzee and chicken species. A number of ADA2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
