In my case I was using MMTV inducible system. I constructed plasmid
that have MMTV promotor and NEO resistance gene simultaneously.
For some reasons, when I done cotransfection with two vectors -
G418 selection will result in obtaining lines without protein of interest.
I used C127 cells. It takes some time to work dexamethasone concentration
in my case the best was 10 -7M.
best luck and let me know if I can be of any help
