Re: hydroxyapatite

From:louise renton

Dear Kathleen

We decalcify our research tissue implants in a formic acid/HCl decalcifier 
(in house recipe) prior to processing for paraffin wax. I do not know the 
composition of our implants (work done before my time), but they appear to 
have a residual structure that remains in the tissue and can be seen when 
staining. You could also try surface decalcifiaction of your blocks. Face 
the block(trim) and then place face down in a coplin jar lid with a little 
of your favourite brand of decal fluid - leave for a while, and then try 
setioning again.
