Hi Daniel,
I haven't seen plastics embedding and microtomy since the mid 90's.
When I was at CCHS in Newark, DE we used to do our bone marrow biopsies in
them. At that time there were molds big enough to embed a penny in.
Yes, you need a different microtome to section these specimens. We had a
glass knife micotome. We had to score and break glass knives at least once a
week. This is a little dangerous and quite tempermental. The edge on the glass
knife didn't seem to last more than 5 days and not everybody was good at making
the glass knives. We adventually, reverted back to paraffin a few years before
I left ('99). If I remember correctly, IHC does not perform well on the
"plastics" specimens which is why we would typically process and embed in
paraffin. We would routinely perform trichrome,PAS and retic on the plastic
sections as well as H&E. I wish I could offer you more information than this.
