[Taxacom] Palcohol?

[John Noyes]

Apart from trashing DNA, it also trashes many types of smaller insects by making them so stiff that the become difficult/impossible to card-mount or put on slides. The same also goes for IMS.

It is my understanding that isopropyl alcohol trashes DNA or otherwise makes it very difficult to extract.  Think on that for pickling museum specimens.  I know of no circumstance where you can get (or ship) isopropyl but not get (or ship) 80-95% ethanol.

Just a thought.   Dan Janzen

And it would no doubt be a more costly alternative.  I think I'll stick with isopropyl alcohol (and a bit of glycerol) for my spider specimens.   In any case, the FDA has apparently already reversed itself and said that its approval of palcohol was an error.
