Proper handling and storage are essential to maintain peptide integrity and ensure reliable research results.
Unreconstituted Peptides (Lyophilized Powder)
Store lyophilized peptides in a freezer at -20°C or below. Keep vials sealed and protected from light and moisture. Avoid repeated freeze-thaw cycles by aliquoting if multiple uses are planned.
Reconstituted Peptides
Once reconstituted with bacteriostatic water or appropriate solvent, store at 2–8°C (refrigerator). Most reconstituted peptides remain stable for 30 days when stored correctly. Check product-specific guidelines for exact stability.
Handling Best Practices
- Allow lyophilized vials to reach room temperature before opening to minimize moisture condensation
- Use sterile technique when reconstituting to prevent contamination
- Label all vials with date of reconstitution and contents
- Avoid exposing peptides to direct light or excessive heat
Following these guidelines helps preserve peptide stability and ensures consistent research outcomes.
