Overview+

Selank is a synthetic analog of the endogenous peptide tuftsin. It is investigated for its influence on anxiolytic and cognitive signaling pathways in neurological research models, and it also shows activity relevant to immune and enzyme-degradation pathways.

History+

Developed at the Institute of Molecular Genetics of the Russian Academy of Sciences, Selank appends a Pro-Gly-Pro motif to the tuftsin core to improve stability. It has been studied as a nootropic and anxiolytic peptide in experimental and clinical settings in Eastern Europe, where much of its characterization took place.

Structure & specifications+
CAS #: 129954-34-3
Formula: C₃₃H₅₇N₁₁O₉
MW: 751.89 g/mol
PubChem ID: 11765600
Research findings+

Selank has been examined in neurological and immune models for GABAergic modulation, serotonergic activity, interferon and cytokine signaling, and enkephalin-degradation effects. Its activity spans both neurological and immune pathways, which is part of what makes the tuftsin-derived structure interesting as a research probe. The Pro-Gly-Pro modification, added for stability, is itself a point of study for how peptide half-life shapes central activity in the laboratory.

Key areas of research
  • →Neurological: Anxiolytic, GABAergic signaling
  • →Immune: Interferon and cytokine modulation
  • →Systemic: Enzyme-degradation and peptide-stability pathways

Frequently asked questions

What's the actual amount in each vial?+
Each vial contains the labeled mass of lyophilized peptide. Selected sizes appear above the price.
Are additional supplies needed?+
Reconstitution requires bacteriostatic water and appropriate sterile research labware – not included.
How long does a vial last?+
Sealed lyophilized vials are stable at −20°C for 24 months. Once reconstituted, store at 2–8°C and use within 28 days.
Does the product come with instructions?+
Each shipment includes the batch-specific Certificate of Analysis and recommended handling protocol.
What purity level is guaranteed?+
≥ 99% by reverse-phase HPLC (UV-220nm), confirmed via ESI-TOF mass spectrometry.
How should I store these products?+
Store sealed vials at −20°C, protected from light. Reconstituted solutions at 2–8°C.
What are peptides and how do they work?+
Peptides are short chains of amino acids that occur naturally in organisms, where they act as messengers in many biological systems. While some peptides have been developed for medical use, laboratory research focuses on understanding their activity at the cellular level, examining how they impact essential processes in vitro.
Do these products come with instructions?+
Products from Fast Track Labs are supplied without usage instructions, as they are designated solely for in vitro laboratory research and prohibited by law for human or animal consumption. Any misuse or unlawful application of these products will result in permanent denial of service.
How long do products take to deliver?+
Orders are typically processed and shipped within 24 hours, Monday through Saturday. Delivery times vary by location, but most domestic orders arrive within 3–5 business days. You'll receive tracking information as soon as your order ships.
