Re: hydroxyapatite

From:Lesley Weston

You might be able to compromise on decalcification. Embed in Epon or one of
the substitutes. Trim and thick section your block to the ROI and then place
the cut face of the block in EDTA for a few hours. Rinse in water and
section immediately. This leaves the area where the hydroxapatite was
undistorted, while still allowing good sections. Hope this helps.
