Since 2006, researchers around the world have been working together to generate a targeted knockout mutation for every gene in the mouse genome. The US component of this effort, The Knockout Mouse Project (KOMP), has been providing critical tools for understanding gene function and the genetic causes of human diseases.
In 2016, the National Institutes of Health funded the next phase in the KOMP project called KOMP2 Phase 2 with the objective to produce and phenotype more than 3000 new knockout mouse lines on a C57BL6/N genetic background. Here at the MMRRC, we are pleased to announce that these KOMP2 Phase2 mouse lines will all be made available from the MMRRC repositories. New mouse lines will be added monthly and full phenotyping data will be available.
Genetically engineered mice serve as valuable models of human disease, contributing to major medical breakthroughs. Often, biomedical researchers must develop unique genetically modified strains of mice for experimentation, a costly and time-consuming process. Now, more researchers in fields from immunology to cancer may be able to save time and money by acquiring genetic material from a repository of previously engineered strains.
The MMRRC distributes and cryopreserves scientifically valuable, genetically engineered mouse strains and mouse ES cell lines with potential value for the genetics and biomedical research community. We are a national network of breeding and distribution facilities plus an information coordinating center serving together as NIH's premier repository of spontaneous and induced mutant mouse and cell lines. The MMRRC is supported by the National Center for Research Resources at the National Institutes of Health. Strains of mice are maintained in a cryopreserved state unless demand warrants that a live colony be established. Live mice are supplied from a production colony, from a colony recovered from cryopreservation, or via micro-injection of a cell line into host blastocysts. At its option, an MMRRC facility may offer cryopreserved material for resuscitation at the recipient scientist's institution. The MMRRC charges fees to partially cover repository costs; please see our Fees page for details.
