Re: [Histonet] mouse heart morphology
Are you freezing inside the cryostat or using a solvent/liquid nitrogen
method, or dry ice/isopentane snap freezing?
When we have frozen mouse heart, for that matter, any murine tissues inside
a cryostat using Peltier device cooling platforms, we get horrible freezing
artifact with terrible morphology. Murine tissue snap freezing tends to be
more stringent, and unfortunately the damage caused by slower, lower
temperture inside cryostat freezing method.
Can you use your device with liquid nitrogen surrounding it? If so, then
murine tissue morphology would be greatly improved.
