Selank
Lyophilized powder • ≥99% HPLC Purity • Ships from U.S. Facilities • Research Use Only
Selank (TP-7, CAS 129954-34-3) is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, developed by the Institute of Molecular Genetics of the Russian Academy of Sciences as a structurally extended analog of tuftsin — a naturally occurring immunomodulatory tetrapeptide derived from the Fc region of immunoglobulin G — supplied by Nextday Peptides in lyophilized format for laboratory and analytical research applications. The Pro-Gly-Pro C-terminal extension was added to enhance metabolic stability compared to native tuftsin. Selank is studied as a research tool for investigating GABAergic neurotransmission modulation, BDNF pathway dynamics, serotonin system interactions, and neuroimmune signaling in controlled preclinical experimental systems. Each vial is independently verified to ≥99% HPLC purity with a Certificate of Analysis available on request. For scientific research use only.
