Shelf Life

The duration a peptide product maintains acceptable quality when stored under specified conditions.

Reference / Full Definition

Handling & Storage

Shelf life is the period during which a peptide maintains its specified purity, identity, and activity under defined storage conditions. For lyophilized research peptides stored at -20°C with desiccant, shelf life is typically 24+ months.

Factors affecting shelf life include: storage temperature (lower is better), moisture exposure, light exposure, oxygen exposure, and the inherent stability of the peptide sequence. Peptides with methionine, cysteine, or tryptophan residues are more susceptible to oxidative degradation.

Reconstituted peptides have dramatically shorter shelf life: days in plain water at 2-8°C, up to 28 days in bacteriostatic water at 2-8°C, or months if aliquoted and frozen at -20°C.

LyophilizationFreeze-drying — a dehydration process that removes water from a frozen peptide solution under vacuum, producing a stable dry powder.OxidationA chemical reaction adding oxygen to peptide residues, particularly methionine, cysteine, and tryptophan, leading to structural modification and loss of activity.DesiccantA moisture-absorbing material (typically silica gel) included with peptide vials to prevent hydration of lyophilized powder during storage.Freeze-Thaw CycleA single event of freezing a peptide solution and then thawing it, which can cause cumulative degradation through ice crystal formation and aggregation.
