Anti-Carbonic Anhydrase I antibodies enable researchers to detect and measure the Carbonic Anhydrase I antigen in biological samples. This target is a reported synonym of the CA1 gene, which encodes carbonic anhydrase 1. This protein is known to catalyze the reversible hydration of carbon dioxide. The human version of Carbonic Anhydrase I has a canonical amino acid length of 261 residues and a protein mass of 28.9 kilodaltons. It is reported to be localized in the cytoplasm of cells and notably expressed in the spleen, rectum, colon, and bone marrow. Other names for this target antigen include CA-I, CAB, and Car1. Western Blot is the most common application for the Carbonic Anhydrase I antibodies listed below. ELISA and Immunohistochemistry are also common applications.
