Regarding Strain Requests

Dr. Blattner retired in July, 2011, and the Blattner lab is closed. Strains, clones, and vectors from its collection are no longer available. Information about their construction continues to be made available for those who obtained strains from us in the past. Anyone who received these materials from us is welcome to redistribute them, so if you see them used in a publication, please contact those authors.

The sequenced E. coli K-12 strain MG1655 is available from both the American Type Culture Collection and the Coli Genetic Stock Center at Yale. Most of the other strains from our genome sequencing projects have also been deposited with ATCC, and genomic DNA from these strains is also available:

Strain ATCC No. Genomic DNA
Escherichia coli K-12 MG1655 700926 700926D-5
Escherichia coli EDL933 700927 700927D-5
Escherichia coli CFT073 [WAM2267] 700928 700928D-5
Shigella flexneri 2457T 700930 700930D-5
Salmonella Typhi Ty2 700931 700931D-5

If you are looking for the reduced genome E. coli strains such as MDS™42, they have been licensed to and are sold by Scarab Genomics, LLC. For more information on reduced genome strain availability, please visit their website.
