Contents Epithalon Form / storage Lyophilized powder; store at −20 °C, protect from light Purity ≥98% — see lot COA CAS 307297-39-8 (free); 307297-40-1 (acetate) Molecular formula C14H22N4O9 Molecular weight 390.35 g/mol Sizes 10 mg Testing Identity (UV/Vis λmax), purity, assay (Beer-Lambert), heavy metals, microbial (TAMC/TYMC) COA Batch-specific — view on this page Research background Epitalon (Ala-Glu-Asp-Gly) was developed in Russia and modeled on the amino-acid composition of epithalamin, a pineal-derived peptide preparation. Its two acidic residues give a net negative charge at physiological pH, and it is highly water-soluble. Scientific interest centers on its investigated influence on telomerase expression, telomere dynamics, and circadian/neuroendocrine regulation in cell and animal models, and it is frequently used as a probe in longevity and chromatin-regulation research. Research applications Cell-model studies of telomerase activity and telomere length Preclinical aging / gerontology research Neuroendocrine and circadian-regulation studies Quality & documentation Every lot is tested by an independent third-party laboratory before it enters the catalog.
