Notice 1/1/2024-- The CGSC at Yale has been discontinued, Strains from the CGSC collection are now available from the E. coli Genetic Resource Center. Questions and correspondence should be directed to john.wertz@ecgrc.net
Notice 10/1/2024-- The legacy CGSC website and Database is in the process of being ported over and hosted at this current ECGRC site. This process is ongoing and we hope to have the process completed in the near future.
INFORMATION ON HOW STRAINS ARE SHIPPED A description of our shipping methods and instructions on how to revive strains can be found here.
Note: The CGSC Collection contains only non-pathogenic BSL-1 laboratory strains, primarily genetic derivatives of Escherichia coli K-12, the laboratory strain widely used in genetic and molecular studies. For details, see About CGSC in the navigation bar on the left.
The CGSC Database of E. coli genetic information includes genotypes and reference information for the strains in the CGSC collection, the names, synonyms, properties, and map position for genes, gene product information, and information on specific mutations and references to primary literature. The public version of the database includes this information and can be queried directly via this CGSC DB WebServer. For help, use the help links located above and on each query form, or contact us via the ECGRC contact page.
