Bacterial cDNA

[Amie Franklin]

I have immunoscreened a cyanobacterial genomic library cloned into stratagene's
lambda ZAP (no affiliation). Protein was being produced in this case so I would
expect the two hybrid approach to work as well. However, there is one important
caveat when trying to express protein from cloned genomic DNA in these vectors.
Very often the protein is constitutively expressed off of its own promoter and
so you cannot discount positives when inducer (IPTG) is not present. 

good luck,
Amie
