Hi,
	 I am getting ready to stain FFPE lung for adenovirus. Is there any
tricks or potential glitches I should know in advance? I will be using a
mouse monoclonal IgG. They do recommend using trypsin, has anyone used
proteinase K instead. I don't want to waste any of this antibody, it is
mucho expensive. So any and all help will be appreciated.  Thanks Jenny
