## Description

Epitalon — also spelled epithalon, and related to epithalamin — is a synthetic four-residue peptide, Ala-Glu-Asp-Gly. Vladimir Khavinson's team in St Petersburg created it as a short synthetic analogue of epithalamin, a peptide extract first obtained from the pineal gland. With a mass of 390.35 g/mol it ranks among the smallest peptides in routine research use, and it is part of the group known as Russian bioregulator peptides.

We produce epitalon by solid-phase synthesis, purify it by preparative HPLC and deliver it as lyophilised powder in a sealed vial. Each lot is tested for purity and identity, and its Certificate of Analysis can be viewed before you buy.

## Frequently asked questions

### What is epitalon?

A synthetic tetrapeptide, Ala-Glu-Asp-Gly, designed as a short analogue of the pineal preparation epithalamin. Laboratories use it to study telomerase activity, circadian signalling and models of cellular senescence.

### Are epitalon and epithalon the same thing?

Yes — epitalon, epithalon and “AEDG peptide” are alternative names for one four-residue molecule. Epithalamin, by contrast, denotes the older pineal extract, not the defined synthetic tetrapeptide.

### How is its purity checked?

Every lot is tested by reverse-phase HPLC for ≥99% purity and by mass spectrometry for identity against the expected mass of 390.35 g/mol. You can view the Certificate of Analysis for the lot on this page before ordering.

### Which vial sizes are offered?

Lyophilised vials of 10 mg, 20 mg and 50 mg. Because the molecule is so small, each milligram contains a relatively large number of moles, and many labs find 10 mg enough for pilot experiments.

### What storage does epitalon need?

Store the lyophilised vial at −20 °C away from light and humidity. After reconstitution, keep it at 2–8 °C in the dark and use it within your validated study period; aliquoting limits damage from repeated temperature changes.
