There was a problem (a while ago) about screening a library and getting a
redundant reduntant clone (was it gal4?).
The question was "is there a way to pre-screen clones?"
Recently, I have experienced the same problem with a different, out of
frame, protein. There is a way to screen your clones before doing large
scale preps and sequencing. Do a restriction analysis of the evil piece of
DNA and digest small scale DH5a (shuttled from yeast). I have managed to
get 4 clones (thank God!) out of 150 that don't resemble the out-of-frame
protein without a lot of extra work.
I hope this will help in some way.
You're not alone...
