To increase the facility and throughput of scoring phenotypic traits in embryonic zebrafish, we developed an automated micro-well assay for heart rate using automated fluorescence microscopy of transgenic embryos expressing green fluorescent protein in myocardium. The assay measures heart rates efficiently and accurately over a large linear dynamic range, and it rapidly characterizes dose dependence and kinetics of small molecule-induced changes in heart rate. This is the first high-throughput micro-well assay for organ function in an intact vertebrate.
