[Histonet] decalcifying embedded tissues

[Krista McCoy]

Hello,

I am studying gonad morphology of frogs.  I usually decalcify then embed 
the whole animal (because they are tiny).  However, I recently forgot to 
decalcify (several samples).  I have ordered and soaked many of my samples 
in RDO, but I am still having a hard time sectioning them.  They are either 
scratched along the surface or "falling out" or the paraffin...

Are their any suggestions on how I can de-calcyfy these specimens?  Should 
I take them out of the block and soak them then re-embed?

Thanks,

Krista
