[Histonet] Freezing muscle biopsies

From:"Osborn, Sharon"

	Our researchers often freeze tissue for later study.  They use the
plastic disposable embedding molds.  These can be used with the dry ice as
John Kiernan suggested. There is a thin layer of OCT placed in bottom of
mold then the tissue is oriented in this with additional OCT to fill the
mold.  The mold can be labeled with a permanent felt tip pen.  Each specimen
is then placed into the labeled sterile sampling bags, packed in dry ice and
shipped to respective location.  We have experienced very little distortion
of the tissue due to ice crystals, etc.  The testing has worked out okay.
The main tissues were liver, kidney, lung.
	You may wish to experiment with some tissues before actually
tackling the research samples to get the right combination for you.

 Hello Histonetters
