Subject: Help, please!!!
Dear Dr Donna,
I am looking for the directions for alkaline phosphatase stain, I have found
information that you use the Bancroft & Cook Method found in the Manual of
Histological Techniques and their Diagnostic Application. I was hoping you
could fax me a copy of this protocol.
It would be greatly appreciated. My fax number is 501-5758490.
Thank you so much!!!
