Toenails do not contain calcium, although an acid may perform some protein 
hydrolysis to break down the protein to may help soften the keratin.  This 
may also damage the antigenic epitope.  Some people use NAIR, or an alkaline 
solution to soften the keratin, beware, high pH also damages alkaline 
sensitive linkages too.

Histonet has many suggestions for softening toenails already, but mostly for 
sectioning purposes.  Check the archives and do a search.

Sounds like a difficult situation for this IHC.

Good luck
