I made a strain GC6 several years ago. It is a recA derivative of GC1 which
was used for years to clone genes from Neisseria. This strain worked when
others would not because it has undocumented mutation(s) in one or more of the
mcr loci and did not restrict cytosine methylated DNA. Now there are many
strains that have all of the mcr loci (and the mrr gene) inactivated. New
England Biolabs has a large collection of strains that they can send you (It
was for free so if they want to charge you, I can send a few). Also, we now
use HB101 since it is missing most of the activities. I hope this helps. Oh
yeh, if you still want GC6 I can send it.
