I am interested in preserving tissue samples from wild amphibians for
later DNA extraction. Any suggestions for an effective preservation
solution?
In particular, I have already mixed a solution of 20% DMSO, 0.25M EDTA,
and NACL sat. I was advised that this might be more effective than 95%
ETHANOL. Is there any reason not to use this solution? Will it work
equally well to preserve nuclear and mitochodrial DNA?
