This Notice updates NOT-DA-08-015.  Under NOT-DA-08-015 Lexicon made over 2,500 knockout mouse strains available for purchase by NIH funded investigators under the same terms as the contract NIH used to acquire knockout mice by using NIH grant money. These mice are no longer available directly through Lexicon but are now being made available through Taconic as the distributor of Lexicon mice  Over 3600 KO mice are available

Under these terms, a NIH investigator acquiring a Lexicon knockout mouse through Taconic using his or her grant funds is expected to place the mouse lines in a NIH-supported mouse repository (see instructions below for submitting to MMRRC).  Universities, medical schools, and research laboratories will have access to mice and germplasm all over the world.  Taconic will send heterozygous mice and materials to the investigator. The investigator and institution will be responsible for coordinating with a NIH supported repository to ensure that banks of cryopreserved embryos, sperm, and embryonic stem cells are archived using state-of-the-art procedures. Mice and cryopreserved germplasm will be available from the central repository for a nominal fee to cover the costs of quality control, archiving, shipping, and restocking the archive. Investigators acquiring mice are also responsible for ensuring that phenotypic data received from Lexicon is deposited in the Mouse Genome Informatics database or another publicly accessible database. All information provided by Lexicon for each mutant mouse will be made available to researchers worldwide without restriction.

In summary, NIH funded investigators may use grant money to purchase Lexicon mice if it is within the scope of their grants.  Those interested in requesting administrative supplements to acquire Lexicon knockout mice should contact their Program Director prior to making a request.  When possible, NIH supported investigators are encouraged to pool resources to share the cost of acquiring a mouse with particular null mutation.  Once an investigator has decided to place an order, he or she should email the completed Terms of Sale found at and purchase order to:
