Name : Human CA9/Carbonic Anhydrase IX Protein
Product Source :
Recombinant Human CA9/Carbonic Anhydrase IX Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Gln38-Asp414.[Accession | Q16790]
Molecular Weight :
The protein has a predicted MW of 43.7 kDa. Due to glycosylation, the protein migrates to 50-60 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Lyophilized from 0.22μm filtered solution in 50mM Tris, 150mM NaCl (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3-6 months after reconstitution.2-8°C for 2-7 days after reconstitution.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Human CA9 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human CA9 is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Human CA9, His Tag at 1μg/ml (100μl/Well) on the plate. Dose response curve for Anti-CA9 Antibody, hFc Tag with the EC50 of 8.0ng/ml determined by ELISA. Bioactivity Data Measured by its esterase activity. The specific activity is > 20 pmol/min/µg.
Background :
CA9 is a member of the Carbonic Anhydrases’ family, that is often expressed in cancer cells under hypoxic condition. CA9 expression potentially contributes to the regulation of cancer cell differentiation and mediates tumour-associated genes and signalling pathways, including apoptosis, hypoxia, G2M checkpoint, PI3K/AKR/mTOR signalling and TGF-beta signalling pathways.
Synonyms :
CA9; CAIX; CA-IX; EC 4.2.1.1; G250; MN; P54/58N; PMW1; RCC
