Product Description

Selank is a synthetic analogue of the immunomodulatory peptide tuftsin. It is a heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. Research has examined its anxiolytic, nootropic, and immunomodulatory properties, as well as its effects on neurotransmitter systems. Selank is structurally related to Semax but targets different receptor pathways, with studies indicating modulation of GABA and serotonin signalling. It is a commonly researched compound in psychopharmacology and immune function studies. Verified at ≥98% purity by HPLC with batch-specific documentation.

This product is intended for in-vitro research and laboratory use only. Not for human consumption.

Research Overview

Selank is a synthetic heptapeptide analogue of tuftsin, an endogenous immunomodulatory peptide derived from the Fc region of immunoglobulin G. Developed at the Institute of Molecular Genetics in Russia, Selank has been studied extensively for its anxiolytic properties, GABA system modulation, and effects on immune function. The compound is often researched alongside Semax — where Semax investigations concentrate on cognitive enhancement and BDNF modulation, Selank research focuses on anxiety reduction, stress response regulation, and GABAergic neurotransmission. Selank has been approved in Russia as a pharmaceutical treatment for generalised anxiety disorder. Research has examined its influence on serotonin and norepinephrine metabolism, its modulation of interleukin expression, and its effects on enkephalin degradation. The peptide's dual anxiolytic and immunomodulatory profile represents a unique pharmacological combination not commonly found in single-molecule compounds. Studies have documented its effects on the hypothalamic-pituitary-adrenal (HPA) axis and its ability to stabilise enkephalins in blood serum, contributing to its anxiolytic mechanism of action.

Laboratory Handling

  • Store lyophilised vials at -20°C. Reconstituted Selank should be refrigerated at 2-8°C and used within 4 weeks.
  • Reconstitute with bacteriostatic water. Swirl gently until fully dissolved — do not shake or vortex.
  • Maintain aseptic technique during handling. Sterilise vial stoppers with alcohol prior to needle insertion.
  • Aliquot reconstituted peptide into single-use volumes to avoid degradation from repeated freeze-thaw cycles.
