RE: [Histonet] overdecalcified bone

Appendix B, p. 445.  


To restore basophilic properties to tissues as the result of
overexposure to decalcifying solution:


Method 1

1.    Deparaffinize and hydrate slides

2.    Place slides in 5% aqueous sodium bicarbonate solution from 4
hours to overnight

3.    Wash in tap water for 5 minutes

4.    Stain as desired


Method 2

In step 2, use 5% aqueous solution of ammonium sulfide overnight


Method 3

In step 2, use 5% aqueous solution of periodic acid overnight


Hopefully one of these methods will work for you.

Hi, Vicki.


Is there a procedure to restore the nuclear staining uptake in

over-decalcified human bone?
