For decalcified bone, an H&E will stain osteoid particularly if the
decalcification has been controlled to not overexpose bone to acid using
endpoint testing. This permits good hematoxylin staining combined with
phloxine/eosin counterstain (don't overstain the bone with this!).
Trichromes also work, Movats pentachrome, Masson trichrome.
For plastic embedded bone, a MacNeals tetrachrome (use inhouse
preparations, commercial ones tend to be lousy for bone), Toluidine blue
in pH 8 phosphate buffer (or a combination of these two stains is brilliant
Sandersons rapid bone stain, will work and/or Stevenels blue, a potassium
permangante oxidized methylene blue. Buy the rapid bone stain and save
yourself grief, making Stevenels is a huge, messy pain in the lab.
Part of seeing osteoid is being able to identify where it is located in the
bone, the microanatomy/micromorphology.
