I've been eluting DNA from agarose gels by taking a plug from the band of
interest, adding it to 100uL water, heat at 60-70C for 10 to 30 minutes.
This works if there is no EDTA in your buffer. From the 100uL water/dna
mixture you would have to make a dilution (I used 1:100) and take 1uL for
If you use EDTA in the buffer you may need some kind of gen clean kit, or
I also use the PCR Preps purification kit from Promega.
