Frequently Asked Questions

Information about our research materials, product documentation, storage, ordering, and research-use requirements.

Peptides are short chains of amino acids linked by peptide bonds, typically consisting of 2-50 amino acids. They serve as the building blocks of proteins and play crucial roles in biological processes.

Research peptides are peptide materials supplied for laboratory and scientific research. They are provided with product specifications and supporting documentation where available, including Certificates of Analysis (COA).

Peptide purity refers to the percentage of the target peptide present in a sample, as measured by the applicable analytical method. Product-specific purity information is provided with the relevant product documentation or Certificate of Analysis (COA), where available.

Product form varies by material. Please refer to the individual product page for the applicable product form and specifications.

Lyophilized peptides:

Store at -4°F for long-term storage (up to 24 months)
Store at 36-46°F (refrigerated) for short-term storage (up to 3 months)
Keep away from light, moisture, and repeated temperature fluctuations
