BrDU monkey inspired non-FACS question... burkes at

The Monkey BrDU thread inspired me to ask a question about a problem I
have been trying to sort out lately. It is not FACS based but I was
hoping someone out there might be able to help. 
    I am going to be injecting mice at time point 1 with BrDU waiting X
amount of time and then injecting IDU at time point 2 with hopes of
seeing different distributions of each in a tumor. 
    The problem I have is that I cannot find an antibody that detects
only IDU. The closest is an antibody that detects both IDU and BUDR
together. I was hoping to stain the tumor for IF with the IDU/BuDR
antibody at 568 nm and then stain for BuDR only with 468 nm and perform
some sort of image analysis/background subtraction.
    First off, the simple answer/question....does anyone know where you
can purchase a monoclonal IDU specific antibody?
    Second...Does anyone know of an easier way to go about this type of
experiment that will not involve tricky background subtraction on tumor
