FOXO4-DRI Storage: Lyophilised vs Reconstituted Comparison

- Lyophilised (pre-reconstitution)
- −20°C to −80°C
- 12–24 months
- Original sealed vial with desiccant
- Store in dark or amber vial
- Stable at −20°C; −80°C extends to 24+ months. Brief room-temp exposure (<30 min) during weighing is acceptable.
- Reconstituted (working solution)
- 2–8°C (refrigerated)
- 28 days maximum
- Sterile sealed vial, preferably amber glass
- Minimise light. UV degrades peptides
- Requires continuous refrigeration. Temperature excursions >8°C accelerate degradation exponentially. Aliquot into single-use vials to avoid freeze-thaw.
- Reconstituted (frozen aliquots)
- −20°C
- 90 days (single thaw only)
- Cryovials, 1 mL aliquots
- Wrap in foil to block light
- Freeze immediately after reconstitution. Thaw once in refrigerator overnight. Never refreeze. Each freeze-thaw cycle reduces bioactivity 15–25%.
