Store lyophilized peptide powder in a cool, dry place.

Recommended long-term storage: –20°C (freezer). Keep vial tightly sealed to prevent moisture exposure. Protect from light, heat, and humidity, as these can reduce stability.

Handling:

• Allow vial to reach room temperature before opening to avoid condensation forming inside.
• Keep away from moisture — lyophilized peptides are highly hygroscopic.
• Avoid repeated vial opening to maintain sample integrity.

General Stability Notes:

• Lyophilized peptides are more stable than liquid peptides, but still sensitive to environmental conditions.
• Product stability may vary depending on sequence and length.
• Always follow documentation such as COA or included storage notes.

After Reconstitution:

• Reconstituted peptide stability varies by product.
• Keep solution cold, protected from light, and use promptly.
• Do not store in warm or humid environments.

Important Notice:

• All peptides are for laboratory research use only.
• Not for human use, veterinary use, or any biological application outside controlled research environments.
