Regarding strain requests: The Blattner lab is closed; strains, clones, and vectors from its collection are no longer available. Information about their construction remains posted for those who obtained them from us in the past. Anyone who received these materials from us is welcome to redistribute them.

We have received a number of inquiries regarding the sequenced E. coli K-12 strain MG1655. We originally obtained the strain from the Coli Genetic Stock Center via Mary Berlyn. When we completed the genome sequence, we redeposited the strain with the Stock Center [MG1655(Seq), CGSC# 7740] as well as with ATCC [ATCC® 700926™]. In addition, the strain was sent out directly from Prof. Blattner’s lab over a number of years. The strain MG1655 is in the public domain, and anyone who received it — whether from us, the Stock Center, or ATCC — is free and clear to use it for research or commercial purposes.

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. For more information on reduced genome strain availability, please visit their website.
