已发表文献
Carbonic Anhydrase (CA) catalyzes the reversible reaction of CO2 + H2O = HCO3- + H+, which is fundamental to many processes such as respiration, renal tubular acidification and bone resorption. Topics in the CA meeting ranged from use of CAs as markers for tumor and hypoxia in clinic, as nutritional supplement in milk, and as a tool for CO2 removal and mosquito control in industry. CA9, also known as membrane antigen MN and renal cell carcinoma (RCC)-associated antigen G250, is a transmembrane enzyme expressed primarily in carcinoma cells. It is one of the best markers for hypoxia and for RCC. rhCA9 corresponds to the extracellular portion of human CA9.

表达区间及表达系统 |
Recombinant Human CA9/Carbonic Anhydrase IX Protein is expressed from HEK293 Cells with His tag and Avi tag at the C-terminal. It contains Gln38-Asp414. |
|
分子量 |
Approximately 43.7 kDa. Due to glycosylation, the protein migrates to 50-60 kDa based on Tris-Bis PAGE result. |
|
纯度 |
> 95% as determined by SDS-PAGE and HPLC. |
|
活性 |
ELISA Data: Immobilized Human CA9, His Tag at 0.9μg/ml (100μl/Well) on the plate. Dose response curve for Anti-CA9 Antibody, hFc Tag with the EC50 of 18.8ng/ml determined by ELISA. |
|
内毒素 |
< 1.0 EU per 1μg of the protein by the LAL method. |
|
制剂 |
Lyophilized from 0.22μm filtered solution in 50mM Tris, 150mM NaCl (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
|
复溶 |
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water. |
运输与保存方法
