Carbonic Anhydrase 2 Protein, Human (His)

Customer Review

Based on 1 Customer Validation

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 (His) is the recombinant human-derived Carbonic Anhydrase 2 protein, expressed by E. coli , with C-6*His labeled tag.

Description

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 (His) is the recombinant human-derived Carbonic Anhydrase 2 protein, expressed by E. coli , with C-6*His labeled tag.

Background

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.

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.22 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.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

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).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. 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.
