This site contains archived older assemblies from the UCSC Genome Browser database. To access newer assemblies, click here. Due to resource limitations, we are unable to provide Blat servers for archived releases.

Note that alignments of genbank sequences will likely not work properly on this site, as the alignments are continuously updated and are not maintained here. Similarly, many links to UCSC and outside sites will likely fail as they age.

The Genome Browser and the data it displays are freely available for academic, nonprofit, and personal use with a few exceptions. Check the README.txt file in the download directory of a particular assembly to view the use restrictions specific to that release. Interactive use is limited to a maximum of 5,000 hits/day or one hit every 15 seconds.
