[Histonet] thick frozen sections

[Charles W. Scouten, Ph.D.]

I agree, on both statements.  Chatter or cracking is usually too cold cutting temperature.  But freezing breaks cell membranes and leaks contents regardless.  If your target protein is in the cytosol, you will much better results without the freezing, sectioning at 100 microns is easy with a vibrating microtome.  See the link below

A vibrating microtome may be superior for this - or you have to warm up the
cryostat chamber in order to cut at warmer temperatures.
