You might try electroelution into buffer. I've seen one protocol in
which you cut a hole downstream of the desired band, and continue
running the gel until the DNA is in the well. But you want to think
hard about what you plan on doing with the DNA after you get it out of
the gel. It certainly will break if you try to pipette it, e.g. You
may want to leave it there, and perform RE digestions, etc. in place,
as described in Birren's books.
