[Histonet] Another plea for human vs mouse

[Jackie.O'Connor <@t> abbott.com]

Hi Y'all - 
I've thrown this question out before, but still don't have an answer. 
Please oh please, if you have an idea, please share!
I'm trying to find an antibody that will specifically identify any and ALL 
human tissue but will not cross react with mouse.
My boss is thinking along the lines of a ribosomal protein - I just look 
at him like a deer caught in the headlights.
We're working with human xenografts in mice.  Since we work with so many 
different tumor lines, from melanoma to prostate, we would like a type of 
broad spectrum antibody that WILL stain human cells but will NOT stain 
mouse stroma, etc.  Any clues??
