Usage of peptide
The product is intended for scientific research and development purposes only. Chemical substances shall not be used as a drug, medicine, active substance, medical aid, cosmetic product, a substance for production of a cosmetic product neither for human consumption that is any food or food supplement or otherwise similarly used on humans or animals. Intended only for in-vitro research, such as Receptor-ligand binding studies, Enzyme activity assays, Cell proliferation assays, Cell signaling assays, Epitope mapping, ect.
Receiving a peptide
Peptides are shipped at ambient temperature by standard shipment process. Peptides are delivered as lyophilized powders. The apparent volume of powder can be variable between 2 vials containing the same quantity. This difference should not be regarded with suspicion. Some peptides, such as short sequences, are highly hygroscopic and therefore can appear as a gel or can be hardly visible.
Storage of lyophilized peptides
Upon receiving the lyophilized peptide, store at 4 °C or colder and away from bright light. Lyophilized peptides are stable at room temperature for weeks, but for longer-term storage, it is safer to store at -20 °C or colder. Exposure to moisture will greatly decrease long-term stability of lyophilized peptides. Before using the peptide, remove from cold storage and allow the peptide to equilibrate to room temperature before removing the lid of the container, in order to reduce the uptake of moisture that is present in the surrounding atmosphere.
Storage of peptide solutions
The shelf life of peptide solutions is limited. Freezing the aliquots will prolong the storage life of the peptide. What is globally accepted for peptides in solution is that they are generally stable for 2-3 weeks at +4°C and for 3-4 months at -20°C. Avoid repeated freeze-thaw cycles, as this can degrade the peptides.
