Detection of Human and Mouse Carbonic Anhydrase II/CA2 by Western Blot.
Western blot shows lysates of human kidney tissue, Caki‑2 human clear cell carcinoma epithelial cell line, and RAW 264.7 mouse monocyte/macrophage cell line. PVDF membrane was probed with 2 µg/mL of Rat Anti-Human/Mouse Carbonic Anhydrase II/ CA2 Monoclonal Antibody (Catalog # MAB2184) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for Carbonic Anhydrase II/CA2 at approximately 27 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Carbonic Anhydrase II/CA2
Carbonic Anhydrase (CA) catalyzes the reversible reaction of CO2 + H2O = HCO3- + H+, which is fundamental to many processes such as respiration, renal tubular acidification and bone resorption (1). Topics in the CA meeting (6th International Conference on the CAs, June 20‑25, 2003, Slovakia) ranged from use of CAs as markers for tumor and hypoxia in the clinic, as nutritional supplement in milk, and as a tool for CO2 removal and mosquito control in industry. CA2 is a cytosolic enzyme with the highest activity among all known CAs. Mutations in the CA2 gene result in the CA II deficiency syndrome, an autosomal recessive disorder that produces osteopetrosis, renal tubular acidosis and cerebral calcification (2).
