About Peptides
What are peptides?
Peptides are short chains of amino acids, typically composed of 2 to 50 amino acids, which are the building blocks of proteins. They play vital roles in biological processes, acting as signalling molecules, hormones, enzymes and structural components within cells and tissues.
How research uses them
Because a peptide sequence can be targeted at one receptor family, laboratories use them to study metabolic regulation, tissue repair, growth-hormone signalling, pigmentation and cellular ageing without the broad effects of larger molecules.
Lyophilised form and reconstitution
Every vial ships lyophilised (freeze-dried) for stability. Stored at 2–8 °C and protected from light, lyophilised peptides remain stable for extended periods; once reconstituted with bacteriostatic water they should be refrigerated and used within the window stated on the certificate of analysis.
Purity and verification
We accept nothing below ≥99% HPLC purity. Each batch is independently tested by HPLC and mass spectrometry, and the certificate of analysis — with lot number and assay date — is available before you order.
