How to Store Research Peptides: Laboratory Best Practices

Research peptides are typically supplied in lyophilised (freeze-dried) powder form for maximum stability during shipping. Once received, most peptides should be stored at -20°C in a laboratory freezer to maintain structural integrity. Reconstituted peptides should be stored at 4°C and used within a defined period depending on the specific compound. Bacteriostatic water is the recommended reconstitution solvent for most research peptides. Avoid repeated freeze-thaw cycles as this can degrade peptide chains and compromise research accuracy.
