For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

Selank is a synthetic heptapeptide analogue of tuftsin, originally developed by the Institute of Molecular Genetics of the Russian Academy of Sciences. It has become a subject of considerable research interest owing to its dual profile as both a nootropic and an anxiolytic compound. Scientists and researchers worldwide continue to investigate its potential to modulate cognitive function, memory formation, and emotional regulation in preclinical models. Direct Anti Peptide offers this compound in a convenient lyophilized vial format, making it a practical and reliable choice for qualified laboratory professionals seeking to buy Selank peptide online at a competitive price.

Peptide Structure & Amino Acid Sequence

Selank is a heptapeptide with the amino acid sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. It is structurally based on tuftsin (Thr-Lys-Pro-Arg), an endogenous immunomodulatory tetrapeptide, with an additional Pro-Gly-Pro tripeptide extension that significantly enhances its metabolic stability and half-life compared to its parent compound. This engineered sequence allows Selank to resist rapid enzymatic degradation, making it a more viable candidate for sustained in vitro and in vivo research applications.

Purity & Analytical Verification (HPLC & MS)

Every batch of Selank Peptide Vial supplied by Direct Anti Peptide undergoes rigorous analytical testing to confirm a minimum purity level of ≥98%. High-Performance Liquid Chromatography (HPLC) is employed to assess chromatographic purity and detect any residual impurities or synthesis by-products. Mass Spectrometry (MS) is used to verify the correct molecular weight and confirm structural identity. These dual analytical methods provide a comprehensive quality profile, ensuring that each vial meets the exacting standards required for reliable and reproducible research outcomes.

Quality Control & Lyophilization Integrity

The lyophilization process used in the preparation of this peptide is critical to preserving its structural and biological activity over extended periods. Freeze-drying removes residual moisture under vacuum conditions, producing a stable, dry powder that is significantly less susceptible to degradation than liquid formulations. Each vial is sealed under inert conditions to prevent oxidation and contamination. Batch-level quality control documentation is maintained to support traceability and research reproducibility. Researchers ordering from Direct Anti Peptide can be confident in the consistency and integrity of every unit received.

Safety, Handling & Laboratory Precautions

This product is intended exclusively for use by trained and qualified research professionals operating within appropriate laboratory environments. Standard laboratory safety protocols must be observed at all times, including the use of appropriate personal protective equipment (PPE) such as gloves, lab coats, and eye protection. Selank Peptide Vial should be handled in accordance with institutional biosafety guidelines. This compound is not approved for administration to humans or animals under any circumstances and must not be used outside of a controlled research setting.

Reconstitution, Packaging & Storage

The Selank Peptide Vial is supplied as a lyophilized powder in a sterile, sealed glass vial. Reconstitution should be performed using laboratory-grade solvents appropriate to the specific research protocol being followed, in strict accordance with established laboratory procedures. Once reconstituted, the solution should be aliquoted and stored at −20°C to minimize repeated freeze-thaw cycles that may compromise peptide stability. Unopened vials should be stored at −20°C away from light and moisture. Proper cold-chain management during transit is maintained to preserve product quality upon delivery.

Intended Research Use & Market Positioning

Selank continues to be a compelling subject of scientific inquiry in the fields of neuropharmacology, cognitive science, and psychoneuroimmunology. Research has explored its potential role in modulating anxiety-related behaviours, enhancing memory consolidation, and influencing immune system signalling pathways in preclinical models. Direct Anti Peptide positions this compound as a premium-grade research reagent for academic institutions, contract research organizations, and independent laboratories seeking a high-purity, analytically verified nootropic peptide for sale at a best-in-class price point.
