General description

Carbonic Anhydrase 2 (CA2) is a zinc metalloenzyme and it helps in regulating acid-base balance in cells. It is a ubiquitous cytosolic protein. Carbonic anhydrase 2 also known as carbonate dehydratase II, carbonic anhydrase C, belongs to the class of a carbonic anhydrases. The associated gene is mapped to human chromosome 8q21.

Application

Carbonic Anhydrase 2/CA2 human has been used for CA2 ELISA (enzyme-linked immunosorbent assay).

Biochem/physiol Actions

Carbonic Anhydrase 2 (CA2) catalyzes the rapid interconversion of carbon dioxide and water to bicarbonate and protons (or vice versa). CA2 can bind to various transporters, such as anion exchanger 1 (AE1), NBCe1 (Na(+)/HCO3(-) cotransporter), NHE3 (Na(+)/H(+) exchanger 3) and MCT (monocarboxylate transporter). This association increases the rate of transport. Mutations in the CA2 gene are responsible for carbonic anhydrase II (CAII) deficiency syndrome, an autosomal recessive osteopetrosis characterised with renal tubular acidosis as well as cerebral calcifications. Changes in the expression of CA2 are linked with carcinogenesis.

Physical form

Lyophilized from 0.22 μm filtered solution in 20 mM Tris, pH 8.0, with 150 mM NaCl, 1 mM DTT. Normally Mannitol or Trehalose is added as protectants before lyophilization.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in sterile PBS, pH 7.4 to a concentration of 50 μg/mL. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, it is recommended to store at -20°C.
