Hello netters- I followed some of the recent thread about the problems with
cloning PCR fragments, and, since I now have the problem, I wish I'd listened
more carefully.  I cut my fragment with the restriction enzymes whose sequence I
believed I had included (with a 5'clamp), but there was no way to be sure they
both worked (SacI and XhoI).  Now I'm not getting inserts into Bluescript II.  A
colleague is having a similar problem with an entirely different sequence and
plasmid.  Was there a summary on the net about solutions?  I did read that
treatment of the Taq-produced fragment with the Klenow fragment of DNA
polymerase solved the problem for some people.  Has anyone else had luck with
that, or can you suggest another solution?
