Checked against PubChem on 27 September 2026. Molar mass is calculated from the formula with standard atomic weights and agrees with PubChem’s published molecular weight. In sequences, H- marks a free N-terminus, -OH a free C-terminal acid and -NH₂ a C-terminal amide.
Research context
Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) modelled on a peptide extract of the pineal gland. It is studied in cultured cells for telomerase (hTERT) expression and activity, and for gene-expression changes in pineal and other cell models.
Research use only. Everything on Vialwise concerns research-grade material sold for laboratory and analytical use only. It is not a registered medicine, is not supplied for human or veterinary use, and nothing here is medical advice.
Storage and handling
Store sealed lyophilised powder at −20 °C, dry and away from light.
Let the vial reach room temperature before opening, so moisture doesn’t condense on the powder.
Short and highly water-soluble, so it dissolves readily in sterile water.
Split the solution into single-use aliquots and keep them frozen, so no portion goes through repeated freeze–thaw.
General laboratory practice for this class of material; your institution’s own procedures come first. To work out concentration and aliquot volumes from a vial’s mass, use the reconstitution calculator. For the reasoning behind each step, read storing lyophilised peptides.
Identity only
Checking a Epitalon COA
Vialwise doesn’t link to a store for Epitalon or list store reports for it. This page covers identity only: the figures a certificate of analysis should agree with, whoever supplied it.
Checks that work on any supplier’s report, and a walkthrough on a real report: how to verify a Janoshik COA.
Any supplier
Check any supplier’s Epitalon COA
These checks take a few minutes and work the same on a report from any supplier. The walkthrough shows each one on a real Janoshik report.
How to verify a Janoshik COAOpen it at the lab
The report should load on the testing lab’s own website from the verify link or task number, not only as a PDF or screenshot from the supplier.
Match the name
The sample should be named Epitalon, Epithalon or Epithalone, or a clear equivalent. A different compound name means a different report.
Match the mass
If the report includes a mass-spectrometry result: a deconvoluted average-mass result should sit close to 390.35 g/mol; high-resolution reports give the slightly lower monoisotopic mass, and raw spectra show m/z for charged ions (mass ÷ charge). How HPLC and mass spec work.
Match the vial
The sample amount on the report should match the vial size you’re buying. A report on a different size or an older batch tells you less about the vial in front of you.
