The AD2 monoclonal antibody binds to human CD73, a 70-kDa glycosyl phosphatidylinositol (GPI)-linked 5’-nucleotidase. CD73, also known as ecto-5’-nucleotidase, has enzymatic activity to convert extracellular adenosine 5’-monophosphate (AMP) to adenosine1,2. It is present in subsets of both T and B cells and at high level on B cells3. It is also expressed on mesenchymal stem cells, follicular dendritic cells, epithelial cells and endothelial cells. The antibody was conjugated to a fluorophore and purified by affinity chromatography.

Each lot of this antibody is quality control tested using flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µL per 1 million cells in a staining volume of 100 µL. If whole blood is analyzed, then use 5 µL per 100 µL. It is recommended that users titrate the antibody to obtain the optimal result for their specific application.
