Carbonic Anhydrase 2 Protein, Human (C-His)

Carbonic Anhydrase 2 (CA2) catalyzes the reversible hydration of carbon dioxide. Mutations in CA2 are linked to osteopetrosis and renal tubular acidosis. The gene exhibits biased expression in various tissues, notably in the stomach and colon. Two transcript variants, encoding different isoforms, have been identified. Carbonic Anhydrase 2 Protein, Human (C-His) is the recombinant human-derived Carbonic Anhydrase 2 protein, expressed by E. coli , with C-6*His labeled tag.

Carbonic Anhydrase 2 Protein is a member of the carbonic anhydrase isozyme family, responsible for catalyzing the reversible hydration of carbon dioxide. Dysregulation of this enzyme is linked to conditions such as osteopetrosis and renal tubular acidosis. Two transcript variants encoding distinct isoforms have been identified. In addition to its fundamental role in carbon dioxide metabolism, the protein exhibits biased expression in various tissues, with notable levels in the stomach and colon, as well as eight other tissues. This tissue-specific expression profile suggests its potential involvement in specialized physiological processes beyond its well-established functions in acid-base balance.

Measured by its esterase activity incubate at room temperature in kinetic mode for 5 minutes. The specific activity is 1851.84-2881.02 pmol/min/μg.

  Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized from a 0.2 μm filtered solution of 20 mM Tris, 500 mM NaCl, pH 8.0 or 20 mM Tris-HCL, 500 mM NaCl, pH 8.0, 8% trehalose, 8% mannitol and 0.02% Tween80.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
