Name : Human CD73/NT5E Protein

Product Source :
Recombinant Human CD73/NT5E Protein is expressed from HEK293 with hFC tag at the C-Terminus. It contains Trp27-Lys547.[Accession | P21589-1]

Molecular Weight :
The protein has a predicted MW of 84.5 kDa. Due to glycosylation, the protein migrates to 85-100 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 20mM Tris, 120mM NaCl (pH 7.5). 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 CD73 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human CD73 is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Human CD73, hFc Tag at 2μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Anti-CD73 Antibody, hFc Tag with the EC50 of 22.6ng/ml determined by ELISA (QC Test). Bioactivity Data Measured by its ability to hydrolyze the 5′-phosphate group from the substrate adenosine-5′-monophosphate (AMP). The specific activity is >10000 pmol/min/μg (QC Test).

Background :
CD73, also known as ecto-5′-nucleotidase, is an enzyme that in humans is encoded by the NT5E gene.CD73 commonly serves to convert AMP to adenosine.The enzyme consists of a dimer of 2 identical 70-kD subunits bound by a glycosyl phosphatidyl inositol linkage to the external face of the plasma membrane. The enzyme is used as a marker of lymphocyte differentiation. A deficiency of CD73 occurs in a variety of immunodeficiency diseases.
