Cutting mouse teeth
Tungsten Carbide knife - embedded in PMMA for microtomed sections, but
teeth must be fixed, PMMA can be removed BEFORE staining - IHC would
require stringent antigen retrieval - Neil Hand has excellent retrieval
method published in J Histotechnology in 1999 or so.
For frozen sections, more difficult to get a good section without
Instrumedics Cryojane tape transfer plus you need to use a tungsten carbide
blade, d profile
You may have results using EDTA decalcification and cut in cryostat. This
can even be done on fresh unfixed or unfixed bone/teeth, fix frozen
sections before staining.
Check out J of Histochemistry Cytochemistry, a recent publication did a
similar method using PLP fixation, etc.
Also Mori S et al J Histochem Cytochem, 36:111-114, 1988 did EDTA on
unfixed fresh bone for cell surface markers.
Not an easy project!
