Assay Method Information

Assay Name:  ADPGlo Assay
Description:  A kinase selectivity panel which measures autophosphorylation using the ADP-Glo Kinase Assay (Promega, V9101) was set-up for wild-type ALK2 (aa172-499) and ALK3 (aa198-525). The assays were performed in 384-well, low volume microtiter assay plates in a final reaction volume of 6 ul. Dose-response curves were generated by incubating 10 nM of each kinase in 50 mM Hepes pH 7.5, 0.02% Tween 20, 0.02% BSA, 1 mM DTT, 10 μm Na3VO4, 10 mM -Glycerolphosphate, 1 mM MgCl2, 12 mM MnCl2 and 15 μm ATP for 60 min at 32 C. in the presence or absence of compound diluted in DMSO. The amount of generated ADP is a measure of kinase activity and is quantified using the ADP-Glo Kinase Assay (Promega) according to manufacturer's instructions. ADP is converted to ATP by adding 3 ul of ADP-Glo Reagent and incubation at 32 C. for 60 min. ATP is subsequently converted into a bioluminescent signal by adding 6 ul luciferase assay reagents (Kinase detection buffer+Kinase Detection Substrate (Promega)) and further incubation at 32 C. for 60 min. For the measurement of luminescence a PHERAstar Multilabel Reader was used at a measurement interval time of 0.1 second (optical module for luminescence measurements in the 230 nm to 750 nm wavelength range).
