[Histonet] EDTA decalcification of bones which have been fixed in 70% ethanol

[Orla M Gallagher]

Dear Histonetters,

We would like to decalcify some mouse bones in EDTA pH 7 which have been
received by our lab already fixed directly in 70% ethanol rather than in
formalin or paraformaldehyde.

How would you recommend preparing these bones for decalcification e.g.
whether to post-fix in formalin or to wash out the ethanol before
transferrring to EDTA? I realise that ethanol is not the best fixative to
use, especially as the end user may want to do immunocytochemistry or enzyme
histochemistry using TRAP.

Thanks,
Orla
