Short-Term Storage - Lyophilized Powder Form Only
- For maximum potency, lyophilized materials may generally be stored between 2°C and 8°C (36°F to 46°F) for up to 4 weeks when maintained in their original, sealed lyophilized form.
- Maintain a cool and dry environment.
- Protect from moisture and light.
- Minimize exposure to humidity and temperature fluctuations.
Long-Term Storage - Lyophilized Powder Form Only
- For maximum potency and long-term preservation, lyophilized materials may generally be stored between -20°C and -80°C (-4°F to -112°F) for up to 1 year when preserved in their original, sealed lyophilized form.
- Maintain a cool and dry environment.
- Protect from moisture and light.
- Minimize exposure to humidity and temperature fluctuations.
Important Note:
Storage guidelines apply only to lyophilized material in its original, sealed, and untampered vial.
