Lyophilized (powder) peptides
Lyophilized describes a freeze-dried form. Appearance and dry form do not establish shelf life; confirm temperature, moisture and light limits in the supplied documentation.
Reconstituted peptides
Solution stability depends on the compound, solvent, pH and formulation. Follow validated conditions; no universal refrigeration or freeze–thaw rule is established here.
Signs a peptide has degraded
- Cloudiness or particles after reconstitution
- Discoloration
- Powder that's collapsed into a sticky film
Frequently asked questions
- Do peptides need to be refrigerated when shipped?
- Confirm validated transit and storage conditions for the actual compound and formulation. Do not assume room-temperature stability from another product.
- Can I freeze reconstituted peptides?
- Only use freezing conditions supported by the specific material’s stability documentation and laboratory protocol.
