Analysts reviewing the HPLC chromatogram for the current batch
FIG. 201Analytical Lab

Identity, purity and main-peak area are checked by reversed-phase HPLC against an in-house reference standard for this sequence. The chromatogram you see on the certificate of analysis is generated at this exact bench, by the analysts who release the batch.

When a sequence moves from milligram research lots to multi-gram research supply, the same chemistry is transferred onto jacketed stainless reactors. Temperature, agitation and reagent equivalents are logged in real time so that the larger batch matches the analytical fingerprint of the small one.

01

Overview

Epitalon is the tetrapeptide Ala-Glu-Asp-Gly, derived from the active structure of the pineal extract epithalamin.

02

Pharmacology and mechanism

Shown in vitro and in animal models to influence telomerase activity, melatonin secretion rhythm and neuroendocrine regulation.
