| Description: | PI3K p110α/p85α (human) was incubated in an assay buffer comprising 10 μM phosphatidylinositol 4,5-bisphosphate and MgATP (concentration as necessary). The reaction was initiated by addition of MgATP solution. After incubation at room temperature for 40 minutes, the reaction was stopped by addition of a solution consisting of EDTA and biotinylated phosphatidylinositol 3,4,5-trisphosphate. Finally, the detection buffer, consisting of a europium-labelled anti-GST monoclonal antibody, a GST-labelled GRP1 PH domain and streptavidin allophycocyanin, was added. The plate was read out via homogeneous time-resolved fluorescence (HTRF) and the corresponding signals were evaluated via the formula HTRF=10000×(Em665 nm/Em620 nm). |
