Lyophilization: why peptides ship as a dry powder

Lyophilization, or freeze-drying, removes water from a frozen sample under vacuum so the solid material is left behind as a stable, dry powder.

Peptides are commonly lyophilized because the dry form is more stable for storage and transit than a solution.

A lyophilized peptide is reconstituted in the laboratory with an appropriate solvent before it is used in research.

Storage guidance for the dry powder is listed on each product page.
