RE: [Histonet] vascular graft_sectioning difficulty

From:"Jack England"

Can you provide a little more information about your processing, and a 
little more detail about how the sections are crumbling (eg, tissue is 
disaggregating, or the paraffin section is falling apart, etc)? We regularly 
section formalin-fixed, paraffin-embedded vascular grafts (ePTFE) at 5-7m, 
and it's working for us.  With a little more information, I might be able to 
help...
