Quick Answer
Peptide purity refers to the percentage of the target compound in the sample, measured by HPLC. Research-grade peptides are typically ≥98% pure.
Peptide purity is determined via High-Performance Liquid Chromatography (HPLC) and expressed as a percentage. A purity of 99%+ means that at least 99% of the material is the intended peptide sequence, with <1% consisting of truncated sequences, deletion peptides, or other synthetic impurities. For research applications, purity directly affects experimental reproducibility. Mass spectrometry (MS) is used alongside HPLC to confirm molecular identity. Third-party Certificates of Analysis (CoA) document both HPLC purity and MS confirmation for each production lot.

What is Semaglutide?Semaglutide is a long-acting GLP-1 receptor agonist with 94% homology to native GLP-1, modified for extended half-life via albumin binding.
How do peptides work?Peptides are short chains of amino acids that bind specific receptors to trigger intracellular signaling cascades, modulating biological processes at the molecular level.
What is Tirzepatide?Tirzepatide is a dual GIP/GLP-1 receptor agonist — the first compound to simultaneously target both incretin receptors for synergistic metabolic research.
How should research peptides be stored?Lyophilized peptides should be stored at -20°C. Reconstituted peptides should be stored at 2–8°C and used within the specified stability window.
