About FlyExpress

FlyExpress is a platform to explore expression patterns of developmentally relevant genes in Drosophila embryogenesis. It contains a unique digital library of standardized images capturing the expression of thousands of genes at different developmental stages. Use our image-matching search engine and genome-scale summaries of spatiotemporal expression patterns (GEMs) to find genes with similar and overlapping patterns of expression in the developing embryo.
