Selank — Tuftsin Analogue

Thr-Lys-Pro-Arg-Pro-Gly-Pro · 10mg Research Vial

Compound Overview

Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) based on the endogenous tetrapeptide tuftsin (Thr-Lys-Pro-Arg), which is derived from the Fc region of immunoglobulin G (IgG). Developed at the Institute of Molecular Genetics, Russian Academy of Sciences, Selank incorporates a C-terminal Pro-Gly-Pro extension for enhanced metabolic stability.

Mechanism of Action

GABAergic Modulation: Preclinical studies have investigated Selank for effects on GABAergic neurotransmission, including GABA transaminase activity and allosteric modulation of benzodiazepine binding sites in rodent brain tissue.

Enkephalinase Inhibition: Research has reported Selank modulation of enkephalin-degrading enzyme activity, potentially influencing endogenous opioid peptide metabolism and turnover in preclinical models.

Immunomodulatory Research: As a tuftsin analogue, Selank has been studied for effects on innate immune function, including monocyte/macrophage activation and cytokine expression profiles in cell culture models.

Frequently Asked Questions

What is Selank?

Selank is a synthetic heptapeptide derived from the human immunomodulator tuftsin (with stabilising N- and C-terminal modifications). It is studied in anxiolytic, immunomodulatory, and nootropic research models, often alongside its sister peptide Semax.

What is the purity of this peptide?

BioCompounds UK supplies HPLC-verified research-grade material. Selected batches undergo independent third-party analysis by Janoshik Analytical, with current published Certificates of Analysis available on our batch verification page when applicable.

What is the half-life of Selank?

Native tuftsin has a very short half-life; Selank’s stabilising modifications extend this somewhat but it remains short-acting (minutes to a small number of hours in published research models). Daily intranasal administration is the most common pattern.

How does Selank compare to Semax?

Both are short Russian-developed regulatory peptides studied in nootropic and neurobehavioural research. Selank is derived from tuftsin and is more often studied in anxiolytic and immunomodulatory contexts. Semax is derived from ACTH(4-10) and is more often studied in cognition and neuroprotection. See our Semax vs Selank comparison.

How should this peptide be stored?

Storage depends on the format you have chosen:

5mg or 10mg Vial (lyophilised powder): Store at -20°C in a sealed container, away from light and moisture. Once reconstituted, keep refrigerated between 2°C and 8°C and use within approximately four weeks.
3ml Cartridge (for reusable pen): Store refrigerated between 2°C and 8°C from arrival. Once opened, use within 3 months. Keep away from light.
Intranasal Research Apparatus (10mg/10ml): Store refrigerated between 2°C and 8°C from arrival. Once opened, use within 3 months. Keep upright and away from light.

Full details are in our Peptide Storage Guide.

What formats is this available in?

This product is available in multiple research formats: a 5mg lyophilised vial, a 10mg lyophilised vial, a 10mg 3ml cartridge for reusable research pens, and a 10mg/10ml intranasal research apparatus. The intranasal format is the most commonly cited in published Selank research literature.

How fast is UK delivery?

Orders are typically dispatched within 24 hours via Royal Mail Tracked 24. During busier periods dispatch may extend to 48 hours. Free shipping on UK orders over £100. Full details on our Postage Guidance page.

Is this product legal in the UK?

All BioCompounds UK products are sold strictly for in-vitro laboratory research by qualified researchers aged 18 or over. They are not approved or intended for human or veterinary consumption, diagnostic, or therapeutic use. See our Terms of Purchase for full guidance.
