Lyophilised Peptides Explained: What Does Freeze-Dried Mean?

What lyophilisation means

Lyophilisation, or freeze-drying, removes water from a frozen material under reduced pressure. In laboratory settings this can produce a dry format that is easier to handle than a solution for some workflows.

The general process

A cycle commonly involves freezing, primary drying by sublimation, and secondary drying to reduce residual moisture. Formulation, container closure and cycle design affect the result.

Dry and solution formats

A lyophilised material and a solution have different physical environments. Stability depends on the compound, formulation, container and conditions. Researchers should use the supplied batch documentation rather than assume that one material behaves like another.
