Subject: Cryostat phenomenon
Has anyone encountered a phenomenon that I occasionally get
with cryostat frozen sectioning. I assume it is due to static
electrical charges? the sections tend to "leap" from the knife edge
onto the slide, the slide may be some several centimeters from the
There is no logic or consistency to this, irrespective of tissue,
fixation, temperature, type of slide; but if it is going to happen then
you can be sure it is when cutting a tiny piece of tissue where
every section is required! It will often disappear as suddenly as it
started, sometimes quite impressive when a section fly's several
cms. to the slide and occasionally lands flat and crease free!
Any idea's?Oh, and I don't wear nylons (not in work anyway).
