Removing Pooled Fat and Mothproofing Freeze-dried Mammals by Perfusion

This article follows up to a short piece that I wrote about ‘lyophiloresistance’ over 10 years ago in Conservation News, 51: 38-39 (1993). It deals with the ongoing problem of removing tris-structured molecular compounds (e.g. dense fluids, such as glycols, and lipids) from freeze-dried biological specimens - particularly mammals.
