STORAGE & HANDLING
Protect identity, dryness, and temperature history.
These are general laboratory safeguards for sealed lyophilized materials. Product- or batch-specific documentation takes priority because stability varies by sequence, formulation, and container.
- On arrival Confirm the product name, strength, seal, and condition before storage.
- Short transit Lyophilized peptides are commonly shipped at room temperature; a 2–7 business day transit period is not the same as long-term storage.
- Long-term default Unless the product record says otherwise, keep sealed lyophilized peptide materials dry, protected from light, and at −20°C or colder.
- Before opening Let a cold sealed vial equilibrate to room temperature before opening to reduce condensation and moisture uptake.
- After preparation Stability becomes product- and solvent-specific. Use validated laboratory procedures, minimize repeated freeze–thaw cycles, and preserve the preparation record.
- Access Keep all materials secured from children, animals, and unauthorized personnel.
