Storage fundamentals
How peptides degrade, and how temperature, light, moisture and freeze/thaw cycles decide how long material stays usable.
- ST-01 How Peptides Degrade: The Chemistry Behind Every Storage Rule Oxidation, deamidation, hydrolysis and aggregation explain why peptides are kept cold, dry, dark and sealed. Knowing which pathway threatens a sequence tells you which precaution matters… −20 °C2–8 °C15–25 °C
- ST-02 Lyophilized Peptides: What the Powder Is and Why It Lasts Freeze-drying removes the water that drives most degradation. Here is what a lyophilized cake is, what can go wrong with it, and how to keep it… −20 °C2–8 °C
- ST-03 Temperature Considerations: Choosing the Right Band Why −20 °C is the default for peptide powder, when −80 °C is worth it, what 2–8 °C is good for, and how to think about… −80 °C−20 °C2–8 °C15–25 °C
- ST-04 Light Exposure: Which Peptides Need Protecting and How Ultraviolet and short-wavelength visible light can oxidize aromatic and sulfur-containing residues. How to tell whether a peptide is at risk, and what amber glass and opaque… −20 °C2–8 °C
- ST-05 Moisture and Humidity: Keeping Dry Material Dry Water undoes the benefit of lyophilization. Where moisture gets in, why opening a cold vial is the biggest risk, and how to use desiccants properly. −20 °C2–8 °C15–25 °C
- ST-06 Freeze/Thaw Cycles: Why Every Thaw Counts Freezing a peptide solution is not a neutral pause. Ice formation concentrates solutes, shifts pH and creates interfaces. How damage accumulates, and how to design a… −80 °C−20 °C
- ST-07 Short-Term Storage: Days to Weeks How to hold peptide material that will be used soon: sealed powder in active use, working solutions for the current week, and material sitting on the… −20 °C2–8 °C15–25 °C
- ST-08 Long-Term Storage: Months to Years Keeping peptide stock usable for months or years: why powder is the best long-term form, when to use −80 °C, inert-gas overlays, secondary containment and planned… −80 °C−20 °C
