Does anyone have suggestions for an IHC stain that will mark ONLY human tumor 
cells?  I have a protocol for ISH with a dig labeled BLUR2 alu probe for use 
in demonstrating cell lines from human brain tumors that have been implanted 
in rats.  The only reason for doing this long and convoluted protocol is to 
demonstrate human tumors, so an antibody would suffice if it only reacted 
with human cells.  Does this ring a bell or gong with anyone?  I am trying 
mightily to save myself from an overly long, tedious project that could 
surely be done another way.
Thanks in advance,
