Ready-to-use ELISA kits are available for the detection of Carbonic Anhydrase XII, an alias of the protein, carbonic anhydrase 12. The official gene symbol is CA12. The kits can detect several species variants of the protein, including: human, mouse, rat, chicken, primate, and other mammalian. The protein, with a mass of 39.5 kDa and length of 354 residues, is reported to be membrane-associated. It is a member of the Alpha-carbonic anhydrase family and may be known by other names, including: HsT18816, CAXII, tumor antigen HOM-RCC-3.1.3, carbonic dehydratase, carbonic anhydrase XII, and carbonate dehydratase XII.
