Synthetic Tuftsin Analogue — Anxiolytic Heptapeptide — 10mg
Selank is a synthetic heptapeptide analogue of the endogenous immunomodulatory tetrapeptide tuftsin, developed by the Institute of Molecular Genetics of the Russian Academy of Sciences. Studied extensively for anxiolytic effects, BDNF upregulation, cognitive enhancement and stress response modulation. Unlike benzodiazepines, Selank does not cause sedation or physical dependence in research models. Independently verified at 98.913% purity by Janoshik Analytical.

About Selank
Selank (TP-7) is a synthetic heptapeptide with the amino acid sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It is a stable analogue of the endogenous immunomodulatory tetrapeptide tuftsin, extended with the Pro-Gly-Pro sequence to increase stability and enhance central nervous system penetration.
Selank has been studied extensively in Russian and international research for its anxiolytic properties, BDNF modulation, cognitive enhancement effects and immunomodulatory activity. Unlike classical benzodiazepine anxiolytics, Selank does not produce sedation, tolerance or physical dependence in research models.
All Pureline Biolabs Selank is supplied as a lyophilised powder in sealed vials, independently tested by Janoshik Analytical at 98.913% purity.

Research Background
Selank has been studied in anxiety research, cognitive neuroscience and immunology. This product is supplied for laboratory research purposes only.
Studies have examined Selank’s anxiolytic effects in rodent models, demonstrating dose-dependent reduction in anxiety behaviours without sedation, tolerance development or withdrawal effects characteristic of benzodiazepine compounds.
Laboratory research has investigated Selank’s effects on brain-derived neurotrophic factor expression, showing significant upregulation of BDNF mRNA in the hippocampus and cortex in animal models — a mechanism of interest for neuroprotection research.
Studies have examined Selank’s effects on learning and memory consolidation in rodent models, investigating its interaction with dopaminergic and serotonergic systems and its effects on working memory performance.
As a tuftsin analogue, Selank has been studied for effects on immune function, including NK cell activity, cytokine production and T-cell proliferation in laboratory models.
Research has investigated Selank’s effects on HPA axis activity and stress hormone regulation, examining its ability to modulate cortisol response and stabilise autonomic nervous system function in stress models.
Studies have characterised Selank’s mechanism of action as an enkephalinase inhibitor, prolonging the activity of endogenous enkephalins and explaining its anxiolytic effects without direct GABA-A receptor modulation.
Store in refrigerator. Keep away from direct light and heat sources.

Stable for up to 24 months when frozen as lyophilised powder.
Standard precautions — keep away from direct sunlight.
Reconstitution Guide
Selank is supplied as a lyophilised powder and must be reconstituted with bacteriostatic water before use in research applications.
Allow vial to reach room temperature. Clean the rubber stopper with an alcohol swab and allow to dry completely.
Draw required volume of BAC water into a sterile syringe. Inject slowly down the inside of the vial wall — not directly onto the powder.
Gently swirl until powder fully dissolves. Do not shake. Solution should be clear and colourless. Selank dissolves readily in BAC water.
