Overheating cut paraffin slides?

From:Kathie Berghorn <kab35@cornell.edu>

Dear Histonetters,
	I am relatively new at using paraffin sections -- I had a 
student cutting paraffin sections over the weekend and to 'help' 
sections dry on the slide warmer after cutting, turned up the slide 
warmer enough that it melted the paraffin around the tissue.

	My question is.... is the tissue still usable?  Did the heat 
damage proteins within the tissue affecting the antigenicity?

	Thanking you in advance f
