I use 5% formic acid, you can make it or purchase Immunocal from Decal
Chemicals, it is slower than the rapid decal solutions but much better for
IHC and FE (although we used to have to do Fe stains on the smears or clot
because besides the decal, iron can be washed out in tissue processing).

Subject: [Histonet] Decal Solution for Bone Marrows

I would be most interested in finding out what other labs are using to
decal the bone marrow biopsy cores.  The current decal solution we are
using is too strong and affecting the Fe stains and some IHC stains.
The decal solution we use for regular bone is great.  Routinely we decal
the core for one hour.  We tried 45 minutes but the cores are still too
crunchy.  And I prefer not to face off the block and float on 5% HCl for
20 minutes.  Thanking you in advance.
