Enhanced amplification of GC-rich DNA with two organic reagents.
Amplification of GC-rich DNA sequences is still a difficult task worldwide. Two frequently seen and inexpensive reagents-ethylene glycol and 1,2-propanediol-were found to be more effective than betaine in the amplification of 104 randomly selected GC-rich human DNA sequences with GC contents of 60-80% and lengths of 700-800 bp.
