I think what we need to know is the controls you made. For example, what is
the transformation efficiency? I cannot believe that you don't get any
colonies using uncut plasmids, so I presume you mean you don't get colonies
from ligation reaction. Is therefore the ligation reaction to blame? Did you
use commercially prepared cells as a control? etc. etc.
