Richard,

It is indeed possible to do "Rapid IHC".  

I have set up "most" of our IHC to work (quite well I might add ;-)) in
about an hour using the Dako Envision kit.  These are PCNA, BrdU, CD3,5,100
several other anti macrophage markers and several more.  Some that take more
time are p53 and LacC. 

I'm lucky enough that I have the time to work out optimal dilution and time
factors.  I also have control over fixation (usually) and work on mostly rat
tissues though I also do some mouse and human.  I don't have ANY control
over the human tissues so I sometimes have to do HIER on them.

best regards,
Bob
