[Histonet] What to do when there is no liquid nitrogen :p

[Meredith Fuller-Fedorczyk]

We send our muscle biopsies to Mayo Labs and they recommend 100% alcohol or
Acetone with dry ice for the slurry. It than can be stored in the -70 degree
freezer.
Isopentane is just so risky to store.

Hi Everyone,

Does anyone have alternate methods for snap freezing muscle when there
is no liquid nitrogen?? I've been told to make a slurry with isopentane
& dry ice or to put isopentane in a plastic cup (?) and put into the
minus 70* freezer till it gets cold. Also how volatile / dangerous is
isopentane to work with??? Other than a flammable cabinet are there any
other things I need to know about isopentane???

Thanks,
Nancy
