Peptide Storage & Handling: A Laboratory Guide
· SupplyPeptides Research Hub
Peptide stability depends on sequence, formulation, temperature, light, moisture, and freeze–thaw history. This laboratory guide covers practical storage and handling principles for lyophilised research peptides. It does not provide human-use instructions.
Lyophilised (dry) storage
Most lyophilised research peptides are held cold — often frozen (e.g. −20°C) — in sealed vials away from moisture. SupplyPeptides holds UK stock in temperature-controlled −20°C storage before dispatch. After receipt, transfer materials into your institutional cold storage promptly and record lot numbers.
After reconstitution
Once reconstituted, many peptides are more sensitive to degradation. Common laboratory practices include:
- Aliquoting to avoid repeated freeze–thaw of a master stock
- Refrigerated or frozen storage per validated SOP
- Protecting light-sensitive sequences
- Clear labelling: compound, concentration, lot, date, RUO
Shipping and cold chain
Short UK transit with insulated packaging is typical for lyophilised vials. Validate receipt temperature expectations against your assay criticality. If a shipment arrives damaged, contact support with the order number before running critical work.

Frequently asked questions
What temperature should lyophilised peptides be stored at?
Follow supplier notes and your institutional SOP. Many lyophilised research peptides are held frozen (e.g. −20°C) before reconstitution.
