CA8, Human

(Carbonic anhydrase VIII, CALS, CARP, CA-VIII, CAMRQ3, CA-related protein, carbonate dehydratase, carbonic anhydrase-like sequence, carbonic anhydrase-related protein.)

CA8 was first called CA-related protein since there is a sequence similarity to other identified carbonic anhydrase genes. Still, this protein has no carbonic anhydrase activity - the reversible hydration of carbon dioxide. CA8 still holds a carbonic anhydrase designation due to obvious sequence similarity to other members of the carbonic anhydrase gene family. Mutations in CA8 result in cerebellar ataxia mental retardation and dysequilibrium syndrome type 3 (CMARQ3).

CA8 Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 314 amino acids (1-290) and having a molecular mass of 35.5kDa. CA8 is fused to a 24 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

Purity: Greater than 90% as determined by SDS-PAGE.

Source: E.coli.

Physical Appearance: Sterile Filtered colorless solution.

Formulation: The CA8 solution (1mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 1mM DTT and 20% glycerol.

Storage:
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles.
