The laboratory rat is an indispensable tool in experimental medicine and drug development due to an extensive knowledge of rat physiology and availability of many disease models. Rat is used extensively as a model organism for studying human normal and disease processes and for testing drug efficacy and toxicity prior to human clinical trials.

This site brings together information about rat data available at NCBI and other related resources from the research community, including sequence, mapping, and clone information. We welcome your suggestions.

Map Viewer
View displays of two annotated rat genome assemblies (RGSCv3.4 and Celera) in addition to radiation hybrid and genetic linkage maps. Take a moment to BLAST your favorite gene sequence against the rat genome sequence and explore the maps available for viewing. Learn more about the Gnomon gene prediction program and the resulting models available in Map Viewer.
