Kate,

i did it many (8) years ago in a osteopetrotic transgenic mouse.  we did do 
long bones to show the   increase in the the number of osteoclasts.  the 
decalcification was slow in EDTA in the cold room.  i hand processed the 
bones and used a special low melting point wax that we got from Merk in 
Germany.
i can't remember the specifics --- the paper citing is:

Soriano P, Montgomery C, Geske R and Bradley A:  Targeted disruption of the 
c-src proto-oncogene leads to osteopetrosis in mice.  Cell 64: 693-702, 
1991.

Hello histonetters-Has anyone done a Tartrate Resistant Acid Phosphatase
stain on rat decalcified bone that was paraffin embedded??  Did it work???
How did you get it to work???  Any help is greatly appreciated.

Thanks in advance,
