A quick BLAST search with the mouse PDI (SwissProt:PDI_MOUSE)
suggests that all mammalian PDI are at least 91% identical (or so.
Hence, any polyclonal serum against one mammalian PDI is likely to
recognize the rest.  

Hamsters are rodents, but I don't know offhand the resolution of
the rat-mouse-hamster trichotomy.  

Good luck!
