Hi Mesru,
1. Cryosectioning followed by Alizarin red staining may work. I'm not
well-versed in this technique, so I will let other experts in this technique
guide you.
2. Alizarin red functions by binding to calcium ions. Acids or chelating
agents used in de-mineralization processes may very well cleave the
alizarin-calcuim bond, resulting in loss of the differentiating stain. If
time, materials and specimens are of a crucial nature, I would not recommend
experimenting with this technique.
3. For years, I have worked with pmma embedded mineralized bone tissues with
much success. There are a variety of stains to assist you in differentiation
of various bone related structures. If you are not well versed with these
techniques, there are labs, myself included, which can give you some pointers
or contract to do the work for you.
Best regards,
Sean
