Research Peptide Storage and Handling
Lyophilized research peptides are usually stored dry, cold, and protected from moisture and repeated freeze–thaw of solutions. Exact temperatures and solvents belong in your lab SOP and on the lot COA, not in a generic blog number copied from a sales page.
Research use only. This is handling documentation for laboratory staff. It is not a use or dosing guide.
As-received (lyophilized)
Keep vials sealed until you are ready to open them in a controlled workspace.
Minimize time at room temperature and avoid condensation when moving vials from a freezer or refrigerator.
Protect from light if the compound or COA notes photosensitivity.
Record lot number, receipt date, and storage location in the lab notebook.
After opening
Once a vial is opened, moisture is the main enemy of a lyophilized cake. Recap promptly. Do not store opened dry peptide at the bench.
Solutions
If your protocol requires reconstitution, document solvent, concentration, date, and aliquot plan. Avoid freeze–thaw cycles on working solutions by aliquoting. Discard solutions according to your institution’s chemical waste rules — do not invent a universal “beyond-use date” from a marketing site.
