Kelly,
Are you using OCT for embedding? Try this: Spin down to a pellet.
Re-suspend in OCT. Spin down again and freeze. Now when you remove the
pellet from the tube the pellet is ready to attach to a cryo-chuck.

We are trying to cryosection samples of brain cells that have been spun
down in a centrifuge tube. The frozen pellets are "popped" out of
the tube, but they begin to thaw when the embedding media is added.
If we tried to use a thinner walled centrifuge tube would it be possible
to section the pellets AND the tube together? We have a cryotome
that used disposable blade, and another that has a stainless blade. I
guess that this is quite possible right, since many of you cut bone, but
would like some tips if anyone has them to offer.
Thanks in advance!
Kelly
