We are a Veterinary Hospital evaluating a Ventana Benchmark LT.  I am 
having a lot of problems staining for S100.  It is very dark with 
background.  The people at Ventana think the secondary antibody is 
cross-reacting and suggest using a different secondary (our secondary 
currently is goat/rabbit).  Can anyone in veterinary medicine help me out 
with this?  So far my experience with this machine has not been 
favorable.  Any advice would be appreciated.
