: Dear Klaus,

: This sounds like a great method for isolating DNA fragments. Have you used
: it on larger fragments, eg 5kb? 

: Also, do you place you tubes containing the melted agarose /DNA, in an
: isopropanol bath, in a -70 freezer?

: Thanks

as far as I remember, the biggest fragment I tried was about 5kb
- no problem.
I usually freeze in liquid nitrogen, dry ice + ethanol does also work.
I didn't compare the yields but had enough fragment with either method.
Hope this helps
