Characterization

What it is, stated plainly.

What it is

A synthetic tetrapeptide, Ala-Glu-Asp-Gly (AEDG). NO DEFINED RECEPTOR HAS BEEN IDENTIFIED FOR IT and no binding partner is established; the published mechanism proposals concern direct interaction with nucleic acid sequences rather than receptor pharmacology. It sits in the telomerase and pineal-peptide literature.

How a lot is verified

Identity confirmed by HPLC and mass-spec; purity assayed by third-party HPLC, with a certificate of analysis published where tested. A lot that misses spec is rejected.

Handling & storage

Supplied as a lyophilized powder. Store at −20°C, desiccated and protected from light. Handled per the receiving laboratory's protocols. Not for human consumption.

Also known asEpithalon · Epithalone · AEDG peptide · Alanyl-glutamyl-aspartyl-glycine

Epitalon (also epithalon; Ala-Glu-Asp-Gly) is a synthetic tetrapeptide modeled on the pineal peptide preparation epithalamin, supplied as a lyophilized powder for laboratory research use only.

It is studied in the research literature in the context of telomere biology and cellular-senescence models. Note that PubChem merges several CAS numbers onto this entry, one of which historically refers to the distinct natural extract epithalamin.

Reported mechanism · literatureReported in cell-based research in association with telomerase-activity and telomere-length endpoints; the summary reflects that literature and makes no claim about outcomes in people.
