Correct storage keeps peptides at the highest possible quality. We recommend a fridge or freezer, although lyophilised peptides are stable at room temperature for up to a month depending on sequence length.
Unopened vials
Store lyophilised powder at 0 to −20 °C for up to 48 months. Best used within 18 months of purchase. If you will use it within 1–3 months, refrigerate instead to avoid repeated freeze–thaw cycles.
Reconstituted solutions
Keep in a refrigerator at 2 to 8 °C and use within 3–8 weeks, depending on sequence.
Best conditions
Keep vials sealed, away from UV light, oxygen and moisture. Moisture and oxygen absorber packets or a vacuum container help.
