Re: [Histonet] Storing frozen TMA sections
We coat our blocks with Instrumedcis Protective Oil that has a freezing
point of -10C. It will not melt the tissue cores in the block and will
prevent dehydration when storing in a freezer for even long periods.
We also coat the blockface when we leave the block in the microtome for next
day sectioning The frozen oil can be sectioned, just like embedding media,
so it can removed and the tissue cores are ready to be sectioned.
