Peptide Storage Guidelines
Detailed temperature, humidity, and handling guidelines for short-term and long-term storage of research peptides in the laboratory.

Introduction
> **Research Context Notice** — This article summarises published scientific literature for educational and research-reference purposes only. Discussion of experimental, preclinical or clinical findings does not represent a permitted use of Novex Peptide products. Products supplied by Novex Peptide are intended exclusively for in-vitro laboratory research and are not intended for human or animal administration.
Proper storage is critical for maintaining the chemical integrity and biological activity of research peptides. Incorrect storage conditions can lead to degradation, oxidation, aggregation, or loss of potency — all of which compromise experimental results.
Temperature Guidelines
Follow the supported product label and compound-specific laboratory protocol. Solution stability depends on the exact material, solvent, concentration and storage conditions; there is no universal refrigerated shelf life or freezing protocol. Obtain missing stability information before preparation. Where validated, use aliquots to minimise repeated freeze-thaw cycles.
Dry-material storage and solution storage are different. Do not infer a one-year shelf life, refrigerated holding time or suitability for freezing from a general article. Use the label and validated stability data.
Moisture and Humidity
Lyophilised peptides are hygroscopic. Moisture uptake can cause hydrolysis and aggregation. Always store vials sealed with the original septum, and use desiccant in storage containers where possible.
Light Sensitivity
Some peptides are photosensitive, particularly those containing aromatic residues (tryptophan, tyrosine, phenylalanine). Store in amber vials or wrap containers in foil. Minimise exposure to direct laboratory lighting.
Oxidation Prevention
Peptides containing cysteine or methionine residues are prone to oxidation. For long-term storage, consider flushing the vial headspace with nitrogen or argon before sealing.
