Why Storage Matters
Peptides are fragile molecules. Heat, light, and repeated freeze-thaw cycles can reduce potency. A simple cold-chain habit protects your research materials.
Lyophilized (Dry Powder) Storage
- Short-term: Refrigerator at 2°C–8°C
- Longer-term: Freezer at −20°C or lower when appropriate for the compound
- Protect from light and moisture
- Let the vial warm slightly before opening to reduce condensation
Reconstituted (Liquid) Storage
- Refrigerate at 2°C–8°C — do not freeze reconstituted solution in most protocols
- BAC water supports multi-draw use better than plain sterile water
- Discard if cloudy, discolored, or particulate matter appears
Light Sensitivity
Some peptides are light-sensitive. Prefer opaque storage when product guidance calls for it.
