Tom Crowell at Biogen in Cambridge, Massachusetts asks:

>>Does anyone have experience performing immunohistochemistry on Davidson's 
fixed
tissue?<<

Davidson's fixative has been discussed repeatedly on Histonet. I probably 
have more information than anybody about its history - see my Web site at
http://members.aol.com/RSRICHMOND/histology.html

but I don't know the answer to this question, and would like to know. - 
Davidson's fixative is made from three parts water, three parts alcohol, two 
parts 37% formaldehyde, one part glacial acetic acid.
