A Certificate of Analysis (COA) is a lab-generated document that details your peptide’s identity, purity, and content. At Midwest Peptide, every COA is produced by Chromate, a trusted U.S.-based laboratory. Each COA includes endotoxin testing to ensure that your research materials meet the highest quality standards.
Peptides should be stored lyophilized (freeze-dried) at -20°C for long-term stability. Once reconstituted, keep them refrigerated between 2–8°C and avoid repeated freeze-thaw cycles. Always store in a sealed vial, protected from light and humidity, to preserve integrity.
Use sterile, high-purity water or the solvent recommended on your COA. Add the liquid gently and swirl until the peptide dissolves. Avoid shaking vigorously, as this may damage the peptide’s molecular structure. Always consult your COA for any specific reconstitution guidance.
Stability depends on storage conditions and peptide composition. Lyophilized peptides stored at -20°C can remain stable for months or even years. Once reconstituted, peptides should be used quickly and stored in a refrigerator at 2–8°C. Before each experiment, verify the peptide’s activity and integrity.
All shipments are protected using shock-resistant packaging with insulation to prevent temperature fluctuations and physical damage. Whether ordering a single vial or a full research kit, Midwest Peptide ensures each product arrives safe, stable, and ready for use.
Yes. Every peptide is tested for purity, content, and endotoxins. Endotoxin testing minimizes contamination risks, ensuring clean and reliable results in research environments.
