question about RFP

Hi, all

I am trying to express RFP in a variety of bacteria species. The broad
host range vector used in my study is a low copy number plasmid. I
wonder whether that was the reason why RFP was not fluoresing after I
transfer the coding sequence into it? I used DsRFP from Clontech. After
cutting with XbaI which produced the insert fragment encompassing the
start and stop codons, I ligated it into pMMB67EH vector. After 3 days
there is still no expression at all. Does anybody know about the copy
number issue in RFP prokaryotic expression? Thanks for any comment and
