Freeze-dried. Peptides are commonly sold in lyophilized (powdered) form to preserve stability during storage. Must be reconstituted before use.
"Lyophilized" is filed under Preparation in the PeptideAtlas glossary, alongside 12 other terms in that group.
The term applies directly to 1 compound profile here: Albiglutide (evidence A). Each profile states the strength of the human evidence rather than only what the compound is claimed to do.
8 other glossary entries refer to this term in their own definition, which is usually the fastest way to see how it is used in practice.
Sterile water containing 0.9% benzyl alcohol as a preservative. Used to reconstitute lyophilized peptides. Unlike sterile water, it inhibits bacterial growth and allows multi-dose use.
The process of adding a solvent (usually bacteriostatic water) to a lyophilized peptide to create a liquid solution for use.
The freeze-drying process used to convert peptide solutions into stable powders for long-term storage. Removes water under vacuum at low temperature, preserving the peptide's molecular structure. Lyophilized peptides can remain stable for years at -20°C.
Water that has been sterilized and contains no preservatives. Unlike bacteriostatic water, it does not inhibit bacterial growth and should be used for single-dose preparations only.
Compounds where this applies: Albiglutide.
