The latter, but we routinely put tissue samples into an aluminium foil
wrap, plop into LN2, and quickly give a few taps with a hammer.
Pulverized tissue is then easy to transfer directly into pestle with cold
lysis buffer, and freezing/pulverizing helps lyse quickly and gets all
your RNAses denatured and inactive.
