Epitalon

Epitalon (also written Epithalon) is a synthetic tetrapeptide with the amino acid sequence Ala-Glu-Asp-Gly (AEDG), used in aging and cellular research. Every lot is finished in the United States from imported peptide API (purified, filled and lyophilized domestically) and tested by an independent laboratory, with the full Certificate of Analysis published and searchable by lot number once the lot ships.

Identity at a glance

• Sequence: Ala-Glu-Asp-Gly (AEDG); single-letter A-E-D-G

• CAS number: 307297-39-8
• PubChem CID: 219042
• Appearance: white lyophilized powder

How it is tested

Epitalon is tested the same way as every product we sell: an independent laboratory (Horizon Analytical) runs ultra-high-performance liquid chromatography for chromatographic purity by area normalization, and mass spectrometry for identity, with the observed mass expected close to the calculated 390.35 Da. No Epitalon lot has been ordered yet, so no certificate is published for it; the certificate for the first ordered lot will appear on the register, searchable by the lot number on your paperwork.
