- Lyophilised at −80°C
- −80°C
- 3–5+ years
- Minimal (hydrolysis nearly halted)
- Requires desiccant, sealed vials
- Long-term archival storage, rare-use peptides
- Gold standard for maximum stability. Overkill for peptides used within 12 months but essential for irreplaceable samples
- Lyophilised at −20°C
- −20°C
- 12–36 months
- Low (some oxidation over time)
- Standard long-term storage for research peptides
- Optimal balance of stability and cost. The default choice for 90% of lab applications
- Reconstituted at 2–8°C
- 2–8°C
- 28 days (bacteriostatic water)
- Moderate (hydrolysis, oxidation, bacterial growth)
- Not applicable (aqueous solution)
- Active-use peptides, short-term protocols
- Practical for ongoing studies. Requires disciplined use-by tracking and single-use aliquoting
- Reconstituted at −20°C
- 3–6 months
- High during thaw (aggregation risk)
- Extended storage when refrigeration insufficient
- Extends usable life but introduces freeze-thaw stress. Only viable with controlled thaw protocols and cryoprotectants
- Room temperature (lyophilised)
- 20–25°C
- 7–14 days max
- High (moisture absorption, oxidation)
- Critical. Desiccant mandatory
- Short-term transport only
- Emergency fallback only. Acceptable for 24–48 hour shipping but not for bench storage
- Room temperature (reconstituted)
- 2–6 hours
- Extreme (rapid bacterial growth, hydrolysis)
- None. Avoid entirely
- Unacceptable for any application. Peptides left at room temp during prep must be used immediately or discarded
