Carbonic Anhydrase 2 Protein, Human (C-His)

Cat. No.: HY-P72860A
COA Handling Instructions

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.

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 (C-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.

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

Lyophilized powder

Formulation

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.

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. 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.

Shipping

Room temperature in continental US; may vary elsewhere.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
