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!!!
