RE: Vibratome

I would agree as it is very difficult to stabilize the specimen and get
consistent sections from a Vibratome.  They can be useful however, one
shouldn't expect the same type of sections as a cryostat or microtome.  The
instrument is not designed for routine use and does require practice to
achieve sections.  Pam Marcum

From my experience it would be next to impossible to cut so thin consistent
sections with vibrotome.
What I would recommend is to cryoprotect your tissue, embed it in O.C.T.
compound and cut it with cryostat.
I also think that 10-20 micron sections would be little too delicate for
free floating work.

I am interested in hearing from anyone versed in the use of a Vibratome.
I have been asked to obtain 10-20 micron thick sections of small pieces (1mm
cubes) of formalin fixed skin. Specifically I would like to know the speed,
amplitude and blade angle you would recommend as well as the method for
embedding the tissue in agarose.  Also, do you use a sapphire knife, a
single edge injector type razor blade or a double edge type razor blade?  Is
it necessary to remove the agarose from the section before staining?  What
type of
slides are best?  Do you prefer staining the free-floating section and then
adhering it to the slide or dry the section on the slide before staining?

Other than that I got it covered!
