Dear Christine:

Would like to recommend method manual written by a good friend of mine
for DAKO.  Called Immunoenzymatic Double Staining Methods, A Practical
Guide.  Got my copy from Europe.  Don't know if it is available now from
the US DAKO group.  Call them at 800-235-5763.  I think some info may
also be available on the histonet archive website,
http://www.pathsearch.com/histonet.html
