[Erratum] Tech News: Cryopreservation
In the December 2008 article by Lynne Ledermann (BioTechniques 45:612), the −130°C temperature referred to the glass transition phase of water rather than the temperature of liquid nitrogen. The sentence should have read:
“In general, liquid nitrogen—with a temperature well below that of the glass transition phase of water (approximately −130°C, the temperature at which frozen water no longer sublimates and recrystallizes)—is used for such long-term storage.”
The HTML and PDF versions of the article have been corrected.
