| | TGFβR1 Kinase Inhibition Assay |
| Description: | TGFβR1 kinase assay was performed according to the instruction manual of the ADP-Glo™ Kinase Assay kit provided by Promega. Prepare 1× Kinase buffer (50 mM Tris pH7.5, 0.1% BSA, 10 mM MgCl<sub>2</sub>, 1 mM DTT). Before activation reaction was started, Compounds were dissolved in DMSO and make 100× solution with 3-fold serial dilution for a total of 10 concentrations. Transfer 50 nL compounds to 384-well plate according to plate map using the automated liquid handler. Prepare enzyme mix containing 2× enzyme mix containing 40 nM TGFβR1 with 1× Kinase buffer, add 2.5 μL enzyme mix to 384-well plate and pre-incubate with compounds at RT for 10 minutes. Prepare 2× substrate mix containing 5.4 μM ATP 1× Kinase buffer and add 2.5 μL substrate mix to 384-well plate, react at RT for 120 min. Add 5 μL ADP-Glo Reagent to terminate the kinase reaction and deplete the remaining ATP, incubate at RT for 60 minutes. Add 10 μL Kinase Detection Reagent to convert ADP to ATP and allow the newly synthesized ATP to be measured using a luciferin reaction, incubate at RT for 30 minutes. Collect luminescence data with Envision. |
