Overview of the screening process 1. You have an idea for a screen 2. First planning meeting -To estimate the feasibility of the project, to give hints about assay development. 3. Assay development 4. Assay robustness and quality testing -The assay needs to fill quality measurements (e. g. Z’-value, signalto-noise ratio) 5. Second planning meeting -To estimate wether screening can be started, planning the scedule 1. 6. Screening 2. 3. 4. -pilot screen -primary screen -(counter screen) 5. 7. Data analysis 6. -identification of hits, pathway analysis, statistical analysis 7. 8. Validation 8. -required for publications www. fimm. fi 20
