Is TRAP is tartrate-resistant acid phosphatase (an
enzyme in osteoclasts; also in osteoblasts near
resorbing bone surfaces)? 

If so, try following up this internet link:

Unfortunately items from the histosearch.com
archives (Histonet questions and answers) are
undated, but none can be more than about 10 years
old! The author of the above link is a bone
expert; she edits the "Hard Times" NSH newsletter.
