The basics of lyophilization

By Carol Horton

Lyophilization, or the process of freeze-drying, is a valuable method for preserving materials for longer-term storage and stability. Similar to cryopreservation, when we talk about lyophilization we focus on the management of water during the preservation process. However, during lyophilization, water is removed through a process called sublimation to yield a stable, dehydrated material with a relatively indefinite shelf-life.

The basics of cryopreservation

By Carol Horton

Preservation becomes essential in the routine maintenance of cultures, allowing us to minimize passage in vitro and preserving valuable stocks used or developed in research. The most common methods of preservation include cryopreservation, which is the process of freezing cultures, and lyophilization, which is the process of freeze-drying material for longer-term storage and stability. Central to both techniques is the management of water during the preservation process. Here, we will discuss the basics of cryopreservation.
