Hi Julie,
It seems to me that a solvent is a solvent is a solvent! The plastic 
beads (polystyrene I suppose?) will dissolve in which ever solvent is 
used to process the tissue. 

Is frozen sectioning out of the question for some reason?

Subject:        	[Histonet] Processing lung tissue after pulmonary function tests

> Histonetters,
