Knockout Mouse Project Repository

Repository of mouse vectors, ES cells, mice, embryos, and sperm generated by the NIH KOMP Mutagenesis Project. In addition, the KOMP Repository offers services in support of the KOMP products, including ES cell microinjection, vector cloning, post-insertional modification of cloned ES cells, cryopreservation, assisted reproduction techniques (IVF, ICSI) and mouse breeding, pathology (clinical and anatomical) pathology services, phenotyping services, etc. The KOMP Repository is the final component of a more than $50 million trans-NIH initiative to increase the availability of genetically altered mice and related materials. The University of California, Davis (UC Davis) and Children''s Hospital Oakland Research Institute (CHORI) in Oakland, Calif., are collaborating to preserve, protect, and make available about 8,500 types of knockout mice and related products available to the research community. The products are generated by two KOMP mutagenesis teams (the CSD consortium and Regeneron Inc). All KOMP products generated by the CSD consortium and Regeneron are available through the KOMP Repository.

SciCrunch Registry

A catalog of scientific resources, with an emphasis on biomedical resources, that is searchable by content and Resource Type, Results are displayed as a list under the Registry tab and as a table under the Data tab (See Registries). Anyone may register a resource to be included in the Registry. All resources undergo curation. NIF catalogs any website that has significant value to the greater scientific community and includes many biomedical resources. For a full description of curation policies and best practices, see Registering A Resource * Through the Resource component of NeuroLex ( * through Register a Resource, Note: The Funding information is often obtained from the associated paper(s) that describes the resource. Mentions of each resource within the Literature are provided by the SciCrunch Registry Automated Crawl Data and can be found in the table view of the Registry. Occasionally, too many PubMed ids are identified and the requested URL's length exceeds the capacity limit for the server. Users will need to crop the URL down to view some of the results at a time. As the system that identifies these resources is an automated system, false positives can occur, especially with resources that are named common names, e.g., ENZYME.
