Active Recombinant Human ENTPD1 Protein, Fc-tagged

Specification :
| Description : CD39, also known as ENTPD1, belongs to the GDA1/CD39 NTPase family. It is expressed primarily on activated lymphoid cells and can also be detected in endothelial tissues.CD39 is involved in the processes of thromboregulation and vascular inflammation . The administration of soluble NTPDase-1 may have therapeutic applications for the treatment of some vascular and transplantation-associated diseases. | Source : HEK293 | Species : Human | Tag : Fc | Form : Supplied as 0.22um filtered solution in 20mMTris,120mM NaCl,4mM CaCl2,20%Glycerol (pH7.4). | Bio-activity : Measured by its ability to hydrolyze the 5’-phosphate groups from the substrate adenosine-5’-triphosphate (ATP). The orthophosphate product is measured by a Malachite Green Phosphate Detection Kit. The specific activity is >5,000 pmol/min/µg. | Molecular Mass : The protein has a predicted MW of 77.3kDa same as Bis-Tris PAGE. Another band is negative Fc. | Protein length : Q39-V478 | Endotoxin : Less than 0.05EU per ug by the LAL method. | Purity : > 95% as determined by Bis-Tris PAGE | Storage : The product should be stored at -70°C. Please do not repeated freeze-thaw cycles. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
