Hi everyone,
            I have been asked to do some frozen sections for a research
project. These specimens need to be frozen into a block , preferably with
the least amount of organic matter involved. Would embedding them in a
saline solution pose any problems ? If this has been done before by anyone,
what concentration have you used/problems did you face? Would anyone be able
to recommend other solutions to use? The routine solution being used in the
lab I have access to , is OTC. Does anyone know the chemical makeup of this
solution (if it is available to the public)?
	Also , I have never done any cutting greater than 7um and I have been asked
to cut these at about 80um . Are there any major problems associated with
thick sectioning.
	Any help at all with this situation will be greatfully appreciated.
