CD39, His-Tag (Human)

Catalog #: 71284
Size: 50 µg
Species: Human
Host Species: Expi293
MW: 51 kDa
Genbank #: NM_001776
Tag(s): C-terminal His-tag
a.a: 38-478

CD39 contributes to immune regulation through the hydrolysis of ATP to AMP in the rate limiting step of extracellular adenosine production. CD39 is expressed on the surface of multiple cells of the immune system including T-cells, Natural killer cells, B-cells, dendritic cells and macrophages. In addition, high levels of CD39 expression have been associated with the tumor microenvironment (TME). Research aimed at reducing immunosuppression by CD39 activity has resulted in the study of a small molecule inhibitor, POM1, and multiple anti-CD39 antibodies selected for blocking enzymatic activity or decreasing CD39 expression. 

CD73/CD39 Immunotherapy

Human CD39, also known as Cluster of Differentiation 39, GenBank Accession number NM_001776, a.a. 38-478 with C-terminal His-tag. MW = 51 kDa, expressed in an Expi293 expression system. This protein runs at a higher MW by SDS-PAGE due to glycosylation.
