Re: Osteoid staining
|From:||Connie McManus <firstname.lastname@example.org>|
A method i have used in the past is a Hematoxylin / phloxine B. For all
intents and purposes, it is an H&E... just substituting the E for Phloxine.
The Phloxine B is prepared in a 0.1% Calcium chloride solution (aq) and is
discarded after use (this solution doesn't keep very well, so I only
prepare the amount I need). The sections stain for 30 minutes in the
hematox, and in the phloxine for 1 minute. Otherwise, it's your garden
