Re: Liquid nitrogen problem
The best way is to use the LN2 / isopentane method. CO2 slush could be
used but it really is not optimal. I'd suggest transporting the biopsy
to your lab on saline dampened gauze on wet ice (water ice). Be careful
not to soak it in saline and under no circumstances should it be
floating in saline.
