Description: | PI3Kδ: Briefly, this assay was conducted in buffer (Tris-HCl 40 mM (pH7.5), Orthovanadate 3 mM, MgCl2 20 mM, DTT 2 mM, CHAPS 0.05%, DMSO 1%). PI3Kδ kinase was added to the reaction solution and mixed gently. The test compounds in 100% DMSO (at specific solutions) were mixed with the kinase reaction mixture to achieve the final compounds at pre-defined concentrations (e.g., range0.5 nM to 100 μM) by Acoustic technology (Echo550; nanoliter range). After incubating for 10 min at room temp, ATP was added into the reaction mixture to initiate the reaction followed by a 30-min incubation at 30° C. After quenching the reaction with ADP-Glo reagent, the plates were incubated for 40 min. The Detection Mixture was added, and the plate was incubated for an additional 30 min. At the end of incubation, luminescence was measured. For data analysis, the luminescence was converted into μM ADP production based on ADP standard curves. |
