[Histonet] "FREEZY" spray

[Jennifer MacDonald]

Based on my limited knowledge of liquid nitrogen I would say no.  Is it 
used with a propellant?

Does this apply to Liquid Nitrogen as well? I'd hate to have to try to cut 
fatty sections in the cryostat without it!

NCCLS Document M29-T (now CLSI)
"Frozen sections done on unfixed tissue pose a high risk because accidents
are common.  Freezing of tissue does not inactivate infectious agents.
Freezing propellants under pressure should not be used for frozen sections
as they may cause spattering of droplets of infectious material."

Based on the above statements, freezing spray should NOT be used in a
cryostat with unfixed tissue.
