Dear Histonetters: After talking to several people & companies, I think
I asked the wrong question as to coming up with any kind of figure for
total amount of tissue use for IHC in the US  would be difficult and
companies view sales figures of AB's as proprietary information.  So my
new questions are: if your institution, research, clinical, animal,
etc.,uses BOTH electron microscopy and IHC testing, what percentage of
your testing is for IHC(light microscopy) and what percentage for EM, or
both(EM IHC).  Has this changed over the last 10 years?  I am doing
research for an article and would appreciate any feedback you out there
doing both EM and IHC can give me.  Thanks in advance,
Tom Kuwahara
