背景介绍 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. 产品介绍 The CD39 Inhibitor Screening Assay Kit is designed to measure CD39 activity for screening and profiling applications. The CD39 assay kit comes in a convenient 96-well format, with purified recombinant CD39 enzyme, ATP, CD39 assay buffer, and Colorimetric detection reagent for 96 enzyme reactions. In addition, the kit includes the CD39 inhibitor POM-1 for use as an inhibitor control.
