Tsu-Hwie,

We use the NaOH extraction method (NAR 1993 21:4153-4154) for PCR or RAPD
on single leaves or even half of a cotyledon. Works great after you find
the optimum dilution for your species. It is also very cheap, easy, and
fast. We have stored extracted samples frozen (-80C) for up to 1 year so
far, and they are still good for PCR.

Good luck!
