Storage Protocols for Lyophilized Powder

Peptides arrive as a freeze-dried powder. Keep them in a dark, cold place. For long-term storage (up to two years), freeze the vials at -20°C.

Once reconstituted, the liquid solution becomes fragile and must be stored in a refrigerator at 2-8°C. Do not freeze the reconstituted liquid, as freeze-thaw cycles break the peptide bonds.

How to Reconstitute Peptides Safely

Let the vial reach room temperature. Clean the rubber stopper with alcohol. Slowly inject bacteriostatic water (0.9% benzyl alcohol) down the side of the vial wall.

Do not spray the liquid directly onto the powder to avoid damaging the compounds. Gently swirl the vial until dissolved. Do not shake the vial.

Common Research Questions

How long do reconstituted peptides last?
Once mixed with bacteriostatic water, reconstituted solutions typically remain stable in the refrigerator for 14 to 30 days.
What solvent should I use for reconstitution?
Bacteriostatic water is the industry standard solvent. The benzyl alcohol inhibits bacterial growth, preserving the solution.
