Hi Histonetters,


I need some advice as my group is tasked to procure tissue from surgery sites 
off-campus.  Logistics within those other hospitals
do not allow a liquid nitrogen source, and my health and safety folks have
asked us to consider using a "Dry Shippers" or cryoport for snap
freezing.  Does anyone do this?  


We are concerned that the vapor alone would be insufficient to preserve RNA,
DNA, and morphology.   


We currently use a dewar for liquid nitrogen preservation, but it does not 
involve the whole 'transport issue'. 



Research or hospital perspectives are welcome.



Thanks in advance and have a good week.
