Selank (10mg) Research Peptide: A Synthetic Heptapeptide for Neuroscience & Cognition Studies

If your research investigates the neurobiology of anxiety, cognitive enhancement, or the complex interplay between the nervous and immune systems, Selank (10mg) research peptide offers a precisely defined and increasingly well-characterised synthetic tool. Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) developed as a structural analogue of the endogenous immunomodulatory tetrapeptide tuftsin. It is a nootropic and anxiolytic peptide that modulates multiple neurochemical systems — particularly the GABAergic, serotonergic, and dopaminergic pathways — without the sedative side effects associated with conventional anxiolytics. This makes Selank (10mg) research peptide a valuable tool for laboratories investigating anxiety disorders, cognitive function, immune modulation, and the bidirectional communication between the brain and immune system.

At Chinese Grey Peptides, we supply high‑purity Selank (10mg) research peptide to research institutions and wholesale buyers across the United Kingdom, France, Germany, Spain, Sweden, Italy, and the USA. Every batch is lyophilised, HPLC‑verified to ≥98% purity, and accompanied by a Certificate of Analysis (COA), ensuring your investigations into neurochemistry, cognition, and neuroimmunology begin with uncompromising quality.

What Is Selank and How Does It Work?

To fully appreciate the research potential of Selank (10mg) research peptide, it is essential to understand its biochemical structure and the mechanisms by which it exerts its neuroactive effects.

The Heptapeptide Derived from Tuftsin

Selank is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP). Its molecular formula is C₃₃H₅₇N₁₁O₉, and its molecular weight is approximately 751.9 g/mol. It has a CAS number of 129954-34-3. As a structural analogue of the endogenous immunomodulatory tetrapeptide tuftsin, Selank was developed through the design engineering of specific physiological functions while retaining the native bioactivity of the parent molecule. It is classified as an anxiolytic and nootropic peptide with anti-stress, antidepressant, and neuropsychiatric properties.

Mechanism of Action: Multi‑Target Neurochemical Modulation

The biological activity of Selank (10mg) research peptide is mediated through several intersecting pathways:

Positive Allosteric Modulation of GABA‑A Receptors

Selank has been shown to affect [³H]GABA binding as a positive allosteric modulator of GABA‑A receptors. By enhancing the inhibitory neurotransmission of GABA, it reduces neuronal excitability and exerts anxiolytic effects without the sedation, motor impairment, or dependence seen with benzodiazepines. The joint action of Selank and benzodiazepines regulates GABA binding in a specific manner that differs from either substance individually.

BDNF Upregulation and Neuroplasticity

Selank protects against memory impairment by regulating brain‑derived neurotrophic factor (BDNF) content in the hippocampus and prefrontal cortex. This upregulation of BDNF supports synaptic plasticity, neurogenesis, and cognitive function.

Modulation of the Endogenous Opioid System

The anxiolytic and behavioural effects of Selank are hypothesised to be mediated by its modulating effect on the endogenous opioid system — specifically, by its effect on the activity of enkephalin‑degrading enzymes. This interaction with enkephalin, a key player in the peptide-mediator cascade, underpins Selank’s regulatory properties.

Immunomodulatory and Cytokine Regulation

As a regulatory peptide derived from tuftsin, Selank modulates the expression of inflammatory cytokines including IL‑6 and TNF‑α, and regulates the expression of inflammatory cytokines and stress‑related hormones. It supports balanced immune function and reduces stress‑related inflammation.

Stress‑Induced Gene Regulation

Selank can regulate stress‑induced processes at the molecular genetic level during the early hours after acute stress, without affecting genomic activity under non‑stress conditions.

Chemical & Physical Specifications for Selank (10mg)

Accurate characterisation of Selank (10mg) research peptide is essential for reproducible experimental design.

Note: The 10 mg mass refers to the weight of the peptide in its lyophilised form. Selank is typically supplied as an acetate salt, which enhances aqueous solubility. Selank is not FDA‑approved for human use and is considered a research peptide elsewhere. Selank is approved for the treatment of Generalised Anxiety Disorder in the Russian Federation.

Reconstitution & Handling Protocol for Selank (10mg)

Proper reconstitution of Selank (10mg) research peptide is critical for maintaining its structural integrity and biological activity.

Step 1 – Preparation

• Bring the sealed Selank vial and your chosen diluent (sterile bacteriostatic water or sterile PBS, pH 5‑7) to room temperature. Condensation can degrade the lyophilised powder.

• Clean your work surface with 70% ethanol and lay out sterile syringes, alcohol wipes and a clean work mat.

Step 2 – Vial Sanitisation

• Wipe the rubber stopper of the Selank vial with a fresh 70% ethanol wipe. Allow the alcohol to evaporate completely before piercing.

Step 3 – Reconstitution

• Draw your desired volume of diluent into a sterile syringe. A common starting concentration for research applications is 10 mg per 1 mL of diluent, yielding a 10 mg/mL stock solution.

• Insert the needle and slowly inject the diluent against the inner glass wall. Do not spray directly onto the lyophilised powder.

• Gently swirl the vial until the solution is clear and fully dissolved. Do not shake vigorously, as shaking can cause denaturation.

Step 4 – Aliquoting & Storage

• Immediately after dissolution, aliquot the reconstituted Selank into single‑use sterile vials.

• Store aliquots at –20°C. Avoid repeated freeze‑thaw cycles, as peptides are susceptible to degradation.

• Once thawed, store at 2‑8°C and use within a short period.

Concentration Reference Table for Selank (10mg)

Adjust diluent volume based on your experimental requirements. For cell culture applications, typical working concentrations may range from 0.1‑10 µM. Preclinical studies have used doses of 100‑300 μg/kg in rodent models.
