How to recover small fragment from agaro

Thu Jul 7 09:17:35 EST 1994

Dear Netters
I separated the 100 bp, 50 bp, and 30 bp DNA fragments with NuSieveGTG
low melting point agarose gel. I want to subclone the 100 bp 
fragment. I tried to purify the 100 bp fragment. However, the recovery 
is very poor (less than 30 %). 
After electrophoresis, I excised the gel band of 100 bp DNA,  melt the
gel at 65 C,  did phenol extraction, and precipitated the DNA with 
ethanol (in 0.1 M NaCl). Does anybody know how to recover small DNA 
from agarose gel efficiently. Please teach me.

Sincerely yours,
