My colleague Jane Silverthorne purchased the E. coli SURE strain from 
Stratagene. They are touting this strain as the ultimate host for
recombinant DNA. 

We have found that this strain carries a single copy of Tn5. Obviously,
this has important ramifications for many recombinant DNA experiments.

Please be advised.
