Thermoelectric freeze‐drying

Journal of Microscopy, 1974
SUMMARYFreeze‐drying is a useful way to maintain the three‐dimensional morphology of biological materials for electron microscopy. The process is achieved simply by utilizing a commercially available thermoelectric unit within a standard vacuum evaporator.

Freezing and freeze-drying

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1975
Most biological substances are unstable during storage owing to their high water content. This is why numerous attempts have been made over the last 100 years to prevent, by low temperature freezing, metabolic and biochemical degradations. The transformation of water into ice brings to an end all chemical reactions; however, it might also induce ...

Freeze-Drying of Proteins

2014
Freeze-drying has become one of the most important processes for the preservation of biological products. This chapter provides protocols for freeze-drying of proteins and discusses the importance of formulation, cycle development, and validation. Specific formulations for stabilization of proteins are presented as well as advice on common problems ...

Freeze-Substitution and Freeze-Drying

1987
Freeze-substitution (FS) and freeze-drying (FD) are dehydration techniques by which the water is gently removed from a frozen specimen. Both techniques can serve as a link between cryofixation and conventional thin sectioning at room temperature (Fig. 1).

Freezing and Freeze-Drying

2016
Freezing of biological materials is commonly carried out to delay biochemical and chemical changes resulting in loss of activity. However, the physicochemical background of freezing is not well understood. Freeze-drying is generally aimed at preserving biological materials and bioactive components for long periods of time without the need for frozen ...
