It has certainly been my (subjective) experience that DNA purified from
acrylamide is easier to clone than DNA from agarose, though I have never
performed a controlled experiment.

As for the purification itself - 3-4 kb is probably too big to elute by
passive diffusion, but I'm sure you could get it out by electroelution.

good luck,
Julian.
