We just got a kit from Promega and upon looking at the matrix solution
I was reminded of a time when I broke up some glass fiber filters
(accidently, Whatman GFC). I wonder if you put some GFC filters in a blender
with 7M GdnHCl whether you would recreate the so called 'magic' resin.
Just a thought. Eric
