Two questions, bit long-winded, so apologies.
I'm looking at samples of cranial bone around an implant made of
polycaprolactone polymer and am currently approaching it in two ways.
1) 4% PFA fixation, formic acid decalcification, cryosections.
2) Ethanol fixation, embedding in Technovit 7100 Glycol methacrylate
resin (Methylmethacrylate resins melt the implant).
Does anyone have a protocol for detection of alkaline phosphatase and
tartrate-resistant acid phosphatase that could be applied to either of
these two section types ??.
I believe the decalcification and formalin fixation may make detection
in the cryo-sections difficult.
Is it likely that we'll be able to cut thicker sections of the Tecnovit
7100 samples on a diamond saw for SEM purposes (2mm thick) ??.
Or is this resin just too soft to support bone plus implants.
Thanks for any help in advance
