Storage & Handling

Storage Conditions

Lyophilized (freeze-dried) peptides are stable when stored correctly, but improper handling is the single biggest cause of degraded purity in research samples.

Before Reconstitution

• Keep vials frozen at −20°C (or colder) until ready for use
• Avoid repeated freeze-thaw cycles — they accelerate peptide degradation
• Allow vials to reach room temperature before opening to avoid moisture condensation inside the vial
• Store away from direct light in the original packaging

After Reconstitution

• Refrigerate reconstituted solutions at 2–8°C
• Use within the timeframe indicated on the batch Certificate of Analysis
• Do not refreeze reconstituted solution
• Handle using standard aseptic laboratory technique to avoid contamination

Shelf Life & Stability

Unopened, properly frozen lyophilized product is generally stable through the date referenced on its Certificate of Analysis. Stability data is lot-specific — refer to the COA shipped with your order for exact figures.
