Hello: Does anyone have any experience with using the Snap-Frost rapid freezing system from Alphelys (France)? Our application is predominantly for tissue banking though we do a booming business in intraoperative diagnosis as well. The company and one review article {Virchow Arch (2008) 452:305-312} claim good RNA/DNA recovery from OCT embedded, isopentane frozen tissue using the system. They also claim good to excellent morphology at -80 in isopentane compared to liquid nitrogen at -190 and especially compared to CO2 freezing. Can anyone confirm or refute the claims? Does anyone know of a US based supplier of the Snap-Frost system? Thanks.
