Storage Finder

Answer a few questions about form, storage time and sequence features to get a starting temperature band and the precautions that apply.

The storage finder gives a sensible starting point based on general peptide chemistry. It does not replace a supplier’s instructions or compound-specific stability data. Where those exist, follow them.

1. What form is the material in?
2. How long until it is used up?
3. How often will you take material out?
4. Sequence features (tick any that apply)

      General guidance from peptide stability literature. The supplier's datasheet and your institution's procedures take priority.

      How the finder decides

      The finder applies the same rules as the guides. Dry powder is the most stable form, so it starts at −20 °C. Solutions held for more than a few days move to frozen aliquots, and those held for long periods or containing oxidation-prone residues move to −80 °C. Sequence features add precautions: Met, Cys and Trp add oxygen and light protection; Asn-Gly and Asp-Gly sites shorten solution use-by periods; hydrophobic or strongly basic peptides add low-binding containers.
