Cloning large inserts into pGEM7F

It depends on how big they are, whether the gene(s) are toxic to E.coli.....
If they're big they could be shearing.  Give me (us) more info either on the 
newsgroup or directly and I'll see if I can help.

I have cloned a 30kb fragment into pGEM 3z but I used a kan gene tagged on it 
to select and maintain it.
