I'm looking for suggestions as my internet searches aren't turning up much.
I'm trying to find a plasmid that has the pBR322 origin, as it's low(ish) copy number and can tolerate large inserts. Additionally I need the plasmid to be inducible with a system other than the pBAD setup (e.g. IPTG would be fine, but if there is one that is more tightly repressed that would be preferrable as IPTG is leaky).
Lastly, I could do with it having a potentially obscure resistance cassette, but this is less of a problem.
Any help appreciated.
