The differential display PCR method (Liang and Pardee, 1992, Science
257,967-971) occasionally discussed in this forum requires that
amplification products of interest are isolated from dried, unfixed,
sequencing gels. Soak the gel piece on the paper backing in water a few
minutes, boil it 15 minutes, recover the liquid, phenol/chloroform
extract, EtOH precipitate with glycogen, and put through two rounds of
amplification of 40 cycles each in order to get enough product to clone.
I've had about an 80% success rate.
