Research peptides are short chains of amino acids synthesised for use in scientific investigation. They are used by laboratories and independent researchers to study biological mechanisms, cellular signalling, and related processes. All products sold by Eterna Peptides are intended strictly for in vitro and laboratory research purposes and are not for human or veterinary use.
Yes. Every batch we stock is tested by Janoshik Analytical, an independent European laboratory specialising in HPLC purity analysis and mass spectrometry for research chemicals. Batch-specific certificates of analysis are published on our Certificates of Analysis page. We do not rely on manufacturer-supplied documentation.
Lyophilised (freeze-dried) peptides should be stored in a refrigerator at 2–8°C for short-term use, or in a freezer at -20°C or below for longer-term storage. Keep vials sealed, away from light and moisture. Once reconstituted, peptide solutions should be stored refrigerated and used within a timeframe appropriate to the specific compound.
Bacteriostatic water (BW) is sterile water containing 0.9% benzyl alcohol, which inhibits microbial growth and is commonly used to reconstitute lyophilised research peptides. We stock bacteriostatic water in our Laboratory Supplies category.
