Understanding how storage temperature affects molecular stability and reconstitution efficacy is critical for research reproducibility.
Introduction
Lyophilization (freeze-drying) is the gold standard for preserving peptide stability during storage and transport. This process removes water from the peptide solution while maintaining its molecular structure.
Key Findings
Recent studies have demonstrated that properly lyophilized peptides maintain over 98% structural integrity when stored at -20°C for up to 24 months. Temperature excursions above 4°C can lead to significant degradation within weeks.
Best Practices
Always store lyophilized peptides at -20°C or below. Use bacteriostatic water for reconstitution. Once reconstituted, store at 2-8°C and use within 30 days.
