I don't mean this to sound condescending, but are you sure that the UV
light transmits through the plastic backing?  If possible, try shining a
UV lamp on the stained gel from above to see if the proteins are
stained.  You may also want to call Pharmacia to see if they have any
ideas about the backing and UV light.  If you do, please be sure to post
the result on the newsgroup.

Best of luck,
