In the Plant Molecular Biology LabFax manual they suggest 20-50 mg per ml in
methanol or 50 mg per ml in DMSO.  They say use freshly. No need to filter
sterilize because the solvent will sterilize it.  Finally they say to store at 
-20 degrees C in the dark.

This is the method we follow.

PS  To all netters: please do not use characters that appear with option or
control keys, they don't translate well over the net.  (Shift key characters are
OK, I believe.)
