| | LanthaScreen Kinase Activity Assay |
| Description: | The enzymatic mTOR activity was measured using a LanthaScreen kinase activity assay (Invitrogen). The enzyme was purchased from Invitrogen (PV4754), as well as the GFP-labelled substrate (4EBP1-GFP; PV4759) and the Tb-antip4EBP1(pThr46) antibody (PV4757). The assay was performed in 50 Mm HEPES buffer, pH 7.5, containing 1.5 mM MnCl2, 10 mM MgCl2, 1 mM EGTA, 2.5 mM DTT and 0.01% Tween-20. The concentration of the assay components were the following: 0.24 nM mTOR kinase, 400 nM 4EBP1-GFP, 10 mM ATP and serial dilutions of the compound (inhibitor) to be evaluated. After 1 h incubation at room temperature, 20 mM EDTA was used to stop the reaction and terbium-labelled antibody (4 nM) added to detect phosphorylated product. The antibody associates with the phosphorylated product resulting in an increased TR-FRET value. The TR-FRET value (a dimensionless number) was calculated as the ratio of the acceptor signal (GFP, emission at 520 nm) to the donor signal (terbium, emission at 495 nm). |
