Hi netters, 
I am trying to reamplify a short (220 bp) band from a PAGE differential
display gel in order to clone it.  I have done this in the past with no
problems by scraping off the band of interest with a clean razor blade,
soaking the piece of gel in 50 ul TE and using 5ul aliquots for the
subsequent reamplifications. The band I am after is quite prominent and I 
have tried several variations on my procedure.
I have not had any success on the subsequent reamplication step with this
particular band.  Any suggestions would be appreciated. 
TIA, Lol
