| Description: | PI3K (p110α/p85α) (h) is incubated in assay buffer containing 10 μM phosphatidylinositol 4,5-bisphosphate and MgATP (concentration as required). The reaction is initiated by the addition of the ATP solution. After incubation for 30 minutes at room temperature, the reaction is stopped by the addition of stop solution containing EDTA and biotinylated phosphatidylinositol-3,4,5-trisphosphate. Finally, detection buffer is added, which contains europium-labelled anti-GST monoclonal antibody, GST-tagged GRP1 PH domain and streptavidin allophycocyanin. The plate is then read in timeresolved fluorescence mode and the homogenous time-resolved fluorescence (HTRF) signal is determined according to the formula HTRF=10000×(Em665 nm/Em620 nm). |
