We are doing exactly that same thing right now. This is changing a 
complete detection system, so we need a full validation (10 pos + 10 
negs for all non-prognostic markers).  To avoid running 20 slides on 
every antibody on our menu ($$$$), we have chosen to use a 3-prong method:

1.  we bought appropriate TMAs from reputable vendors (such as 
Pantomics, Inc)  which will provide more than 10 Pos +10 neg for most cases.
2.  we made a universal "negative" control with 12 different tissues 
from our collection (provides tissues processed by us)
3.  we run 1(or 2) of our control slides (bonus: also validates the 
control at the same time)

This way we only run three slides for each validation to get the 
required number of tissues - big difference in workload and cost!

Hello all,

Our lab is getting ready to switch from using the iview DAB to the
ultraview - any tips for validation?  How many cases did you run for each
