Does anyone have experience if a single copy gfp gene inserted into chromosome of bacteria is able to produce enough fluorescence to be visible in fluorescent microscope?
Yes it does if it is combined with a strong enough promoter that ensures sufficient expression...
Thanks. How do you rate bla promoter for such case ?
I am trying to induce pBAD promotor. The plasmid with this promotor was inserted into a wild type E. coli by electrotransformation. I tried several different concentration of arabinose but no...
