[Histonet] viability question

[Fawn Jones]

Dear histonetters,

I am looking for some information for a friend.  She wants to find out 
if her tissues (aortas) are live or not.  Does anyone have any 
experience performing viability stains on tissue samples?  She tried the 
Molecular Probes Live/Dead kit but found it insufficient due to 
permeabilty issues. She also suggested MTT, but we're not sure how well 
that stain works with tissues.  Any help would be greatly appreciated.

Thank you
