| Description: | For measurements of soluble CD73 enzyme activity, recombinant CD73 was obtained from R&D Systems, Cat. No. 5795-EN-010. Serial dilutions of test compounds were incubated with recombinant CD73 and AMP in reaction buffer (25 mM Tris HCl pH7.5, 5 mM MgCl2, 50 mM NaCl, 0.25 mM DTT, 0.005% Triton X-100). The final reaction volume was 25 μL and the final concentrations of recombinant CD73 and AMP were 0.5 nM and 50 μM, respectively. Reactions were allowed to proceed for 30 minutes at room temperature before the addition of 100 μL Malachite Green (Cell Signaling Technology, Cat. No. 12776). |
