Is your problem with all your antibodies or only a few?  Do you see it
more often with tissues that contain an abundance of the antigen that
your are staining for?

We are periodically getting uneven staining patterns on our IHC
slides.
I have exhausted my troubleshooting skills and need input from anyone
out there who may be able to help.  We are using the Dako Autostainer
(2
different ones).  I have checked the leveling, reagent distribution,
and
slide position.  I am in a reference laboratory and unable to do much
in
terms of trouble shooting fixation, etc.   I am at wit's end and will
happily provide any other details to assist.  Dako says they are
clueless and have heard no other similar complaints.  Please help. 
TIA.
