RE: [Histonet] Frozen section of plastic stent

From:"Alan Bright"

Dear Cathy & others with this problem,

I do not know the answer to your problem with sectioning plastic
(silicone) stents, but I have experience of sectioning a wide range of
materials including plastics. If you could send me a sample I would be
very happy to section the stent and give you a full report with no costs
to you. I am hoping that all that is required is determining the correct
temperature and maybe using a tungsten carbide tipped knife.

Best Regards

Subject: [Histonet] Frozen section of plastic stent

Happy New Year Histonetters!!
Any suggestions for cutting plastic (silicone) stent embedded in OCT on
the cryostat.  I'm cutting at 10 microns, -28 C and about every third or
fourth section is good.  I am moving the blade every 20-30 sections.
Most of the sections are badly folded or fractured.  The stent will
eventually be part of tissue, farther into the block. Thanks in advance
for the help. Cathy
