Ventana system is nice for IHC and specials, must use their detection,no room 
for tweaking on special stains, expensive on specials , can run IHC overnite 
cannot run specials overnite.
Cytologix can run IHC and specials together, more open architecture, temp 
control on each well(ventana at constant 37 degree),, less expensive 
reagents, quality of stain excellent on both IHC and specials, can run both 
IHC and specials overnite.
Cytologix instrument has 48 slides slots, ventana each module 20, have to add 
on modules.                                    Dana
