As long as you don't need to use them for RNA analysis, the easiest thing to do
is just rub your finger (without glove) across the block (very briefly) and
then take the section. This will probably do the trick and hydrate it just
enough to make a difference.
Kim
Kim Merriam, MA, HT(ASCP
Also, make sure that the block sits in the cryostat for a while to acclimate to
the temperature. The cutting temp for lung (correct me if I'm wrong here) is
probably about -20; the block should be the same temperature as the cryostat.
