Just to explain to people who've never had to do co-expression - if I remember correctly, conventional wisdom states that you can't have two different vectors with the same origin of replication in the same host (maybe someone might know more details as to why). However, as pointed out, it can be made to work.

Alas, not in my case!

We have had good experience with the awfully simple minded approach of using two pET vectors with different antibiotic resistance.Its the easiest thing to do, and it often works ...
Apologies for the shameless plugin, since there are many good papers on the subject, but you can read some hints and case studies at:

If you are expressing just two proteins, you could try a single pET vector with a pCDF vector. The only reason I'm suggesting this is that I had trouble with pET-Duet, but doing each one separately worked first time (plasmid size issue?). I used pET24-a and pCDF-1b - so I had one construct untagged, and the other with a cleavable His-tag.

Cheers

Dear All,Anyone have experience with the NovaGen Duet co-expression vectors? Or can recommend others?
