Try TRIzol reagent available from GIBCO BRL (no affiliation) and others
using different brand names.  This proceedure also allows for the isolation
of DNA (+ RNA + proteins) from the same sample.  This method works great and
is fast (3 hours, 1 hour for RNA)

See Chomczynski, Piotr.  "A Reagent foe the Single-Step Simultaneous
