Cutting paraffin blocks in a cryostat

From:Andrew Gray <>

Hello Histonetters,

A question from a newbie to the list.   I was wondering if anyone knew
if it is possible to cut paraffin blocks in a cryostat.   I have access
to a Leica CM 1850 cryostat and I wish to examine some soft tissues of
rats.   Paraffin is preferable for handling and storage reasons, but I
don't have access to a standard microtome.   The mechanics of a cryostat
seem essentially the same, but I was wondering about the practicalities
of using it in this way (e.g. the appropriateness of the blade, holding
the block in position with the adhesive, temperature etc.).

Thanks in advance,
