Pinealon
Lyophilized powder • ≥99% HPLC Purity • Ships from U.S. Facilities • Research Use Only
Pinealon (EDR, Glu-Asp-Arg, CAS 175175-23-2) is a synthetic tripeptide with the amino acid sequence L-Glutamic acid–L-Aspartic acid–L-Arginine, developed by Professor Vladimir Khavinson and colleagues at the Saint Petersburg Institute of Bioregulation and Gerontology as part of the cytogen class of short peptide bioregulators, supplied by Nextday Peptides in lyophilized format for laboratory and analytical research applications. Originally isolated from brain cortex peptide extracts (Cortexin) rather than the pineal gland itself, Pinealon is studied as a research tool for investigating neuroprotective signaling, oxidative stress response, dendritic spine biology, and circadian rhythm-associated gene expression dynamics in controlled neural cell and preclinical experimental systems. For scientific research use only.
