I am trying to get hold of a plasmid with an amber mutation in the
ampicillin gene. I have the bacterial strain MC1061/p3 which has a P3
episome but I would prefer to select for the presence of supF directly.
This episome is at v low copy number and I dont have a map so I cant clone
Apparently propagating the vector pivx requires the presence of such an
amber mutated plasmid. Can anyone help?
