Please note that the archive website for Ensembl release 53 (March 2009) will be retired next week when version 67 is released.

This is in accordance with our rolling retirement policy, whereby archives more than three years old are retired unless they include the last instance of the previous assembly from one of our key species (human, mouse and zebrafish). Since zebrafish is currently on assembly Zv9, the e53 archive (which contains the last instance of Zv7) is not being retained under these rules; however the Zv7 assembly will be available on archive 46 until a new version of the mouse assembly is released this summer.

For more information about how to use archives, please see our previous blog post on the topic; a list of all current archives is available on the main website.
