Research overview

Selank is a synthetic heptapeptide built on the amino acid sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP). It is catalogued under CAS 129954-34-3 with the molecular formula C33H57N11O9 and a molar mass close to 751.9 g/mol. The molecule was designed as a synthetic analog of tuftsin, a short naturally occurring peptide fragment, extending the tuftsin core with additional proline and glycine residues. As a compound, Selank is referenced across neuropeptide chemistry and behavioural neuroscience research literature, where synthetic tuftsin analogs are examined as model peptides. It also turns up in the broader literature on short regulatory peptides and their structure. These references describe the research fields in which the molecule appears and are provided for context only. We supply Selank as lyophilized reference material in 5mg and 10mg vials, offered strictly for laboratory research use only and not for human or veterinary use. Every lot is third-party tested, and each order ships with an independent per-lot certificate of analysis (COA). Researchers looking to buy Selank in Canada can order from Kits Peptides in Vancouver, with tracked shipping to labs across the country.

Selank is a synthetic tuftsin-analog heptapeptide (TKPRPGP) that appears in neuropeptide chemistry and behavioural neuroscience research literature. Supplied as a reference standard for laboratory research use only, lot-numbered, with an independent COA published for any lot that has been analysed.
