- Lyophilized (unopened)
- −20°C to −80°C
- 12–24 months
- Vacuum-sealed vials maintain potency; avoid freeze-thaw cycles
- Reconstituted (refrigerated)
- 2–8°C
- 28–30 days
- Use within 30 days; bacterial growth accelerates beyond this window even with bacteriostatic water
- Reconstituted (frozen aliquots)
- −20°C
- 90–120 days
- Single-use aliquots only; each freeze-thaw cycle reduces potency 5–10%
- Ambient temperature exposure
- 20–25°C
- 24–48 hours max
- Protein denaturation begins above 8°C; irreversible after 72 hours
