Anti-Human CD73 eFluor® 450

Description: This AD2 monoclonal antibody reacts with human CD73, a 5’-ectonucleotidase that converts 5’-adenosine monophosphate to adenosine. CD73 is expressed on the surface of endothelial cells, as well as B and T cells, including some CD4+Foxp3+ regulatory T cells. Adenosine production by these cells has been linked to the inhibition of CD4 T cell effector functions such as proliferation and cytokine secretion.
