- To further illustrate the critical role of proper technique, we've put together a comparison of common reconstitution methods and their typical effects on peptide stability, particularly relevant for understanding AOD-9604 degradation reconstituted:
- Sterile Water
- Good for immediate use, but limited long-term stability. Accelerates hydrolysis over time.
- Use for immediate experiments. For storage > 24 hrs, consider other options.
- Bacteriostatic Water
- Enhances short-to-medium term stability (weeks/months) by inhibiting microbial growth.
- Ideal for multi-dose vials. Store refrigerated (2-8°C).
- Acetic Acid (0.1% – 1%)
- Can aid dissolution for some difficult peptides. Increases risk of hydrolysis.
- Use only if specified for peptide. Avoid for AOD-9604 unless research dictates.
- High pH Solvents
- Significantly accelerates deamidation and hydrolysis.
- Avoid for most peptides, especially AOD-9604, due to rapid degradation.
- Vigorous Shaking
- Induces aggregation, oxidation (foaming), and shear stress.
- Gentle swirling only.
- Room Temp. Storage
- Rapid degradation (days to weeks).
- Acceptable only during reconstitution process. Immediately refrigerate or freeze.
- Freeze-Thaw Cycles
- Extremely detrimental. Causes denaturation and aggregation.
- Aliquot into single-use vials before freezing to prevent repeat thawing.
