DatasheetSpecific ReferencesReviewsRelated ProductsProtocols
Mouse CA12 Protein Product Information
Synonym:Car12, 2310047E01Rik, AI314958
Protein Construction:A DNA sequence encoding the extracellular domain (Met 1-Ser 301) of mouse CA12 (NP_848483.2) precursor was expressed with a C-terminal polyhistidine tag.
Expressed Host:Human Cells
Shipping:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Mouse CA12 Protein QC Testing
Purity:> 95 % as determined by SDS-PAGE
Bio-Activity:Measured by its esterase activity. The specific activity is >50 pmoles/min/μg, as measured with 1 mM 4-Nitrophenyl acetate and 0.4 μg enzyme at 400 nm in 100 μL of 12.5 mM Tris, 75 mM NaCl, pH 7.5.
Endotoxin:< 1.0 EU per μg of the protein as determined by the LAL method
Stability:Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N Terminal:Ala 25
Molecule Mass:The secreted recombinant mouse CA12 consists of 288 amino acids and has a calculated molecular mass of 32.8 kDa. As a result of glycosylation, the recombinant protein migrates as an approximately 40-45 kDa protein in SDS-PAGE under reducing conditions.
Formulation:Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
Mouse CA12 Protein Usage Guide
Storage:Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution:A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

Carbonic Anhydrase XII Background

Carbonic anhydrases (CAs) are a large family of zinc metalloenzymes first discovered in 1933 that catalyze the reversible hydration of carbon dioxide. CAs participate in a variety of biological processes, including respiration, calcification, acid-base balance, bone resorption, and the formation of aqueous humor, cerebrospinal fluid, saliva, and gastric acid. CA12, also known as Car12 and carbonic anhydrase XII, is a type I  membrane enzyme of an N-terminal extracellular catalytic domain, a membrane-spanning α-helix, and a small intracellular C-terminal domain. It is highly expressed in colon, kidney, prostate, intestine and activated lymphocytes and moderately expressed in pancreas, ovary, and testis. Overexpression of the CA12 is observed in certain human cancers and is used as a tumor marker. rmCA12 corresponds to the extracellular domain and has both carbonic anhydrase activity and esterase activity.
