[0393] A. Procedure for High Throughput Screening

[0394] 1. Synchronized embryos are distributed into 96-well assay plate. Embryos developmental stage (age) can be synchronized by treating the adult fish with propidium iodide, and stimulating them to lay egg in a predicted time frame. Embryos can be distributed using an automated particle handling devices equipped with a light scattering detection system (BD Biosciences, Bedford, Mass.). The particle handling device should preferably be capable of dispensing up to 600 μm particles. Alternatively a liquid dispenser fitted with large bore pipette tip can be used to dispense embryos into microtiter wells automatically.

[0395] 2. 100 μl of diluted compounds are added to each well (in fish water). An automatic microplate pippetting and washing workstation (Zymark, Hopkinton, Mass.; Packard Bioscience, Groningen, The Netherlands) can be used. A simple bar code system to identify each plate (Decitek, Westborough, Mass.).
