Recombinant Human Carbonic Anhydrase II/CA2 Protein (His Tag)(Active) Size: 100μg Catalogue Number: PKSH031582-100 Citations, Manuals and MSDS Available upon request. Abbreviation: Carbonic Anhydrase II; CA2 Target Symptom: CA-II; CAC; CAII; Car2; HEL-76; HEL-S-282 Research Area: Cell biology; Cardiovascular Target Species: Human Expression Host: E.coli Application: Enzyme Fusion Tag: C-His Accession: NP_000058.1 Background: The carbonic anhydrases (or carbonate dehydratases) are classified as metalloenzyme for its zinc ion prosthetic group and form a family of enzymes that catalyze the rapid interconversion of carbon dioxide and water to bicarbonate and protons, a reversible reaction that takes part in maintaining acid-base balance in blood and other tissues. The carbonic anhydrasekl (CA) family consists of at least 11 enzymatically active members and a few inactive homologous proteins. Carbonic anhydrase II is one of fourteen forms of human α carbonic anhydrases. Defects in this enzyme are associated with osteopetrosis and renal tubular acidosis. Renal carbonic anhydrase allows the reabsorption of sodium ions in the proximal tubule. Carbonic anhydrase II has been shown to interact with Band 3 and Sodium-hydrogen antiporter 1. Activity: Measured by its esterase activity. The specific activity is > 150 pmoles/min/μg. Sequence: Met 1-Lys 260 Purity: > 96 % as determined by reducing SDS-PAGE. Formulation: Lyophilized from sterile 20mM Tris 0.5M NaCl, pH 8.0 Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
