Re: Osteoid staining

From:Connie McManus <>

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
variety H&E.
