Selank is a synthetic heptapeptide studied in neuropeptide signalling research.\u003c\/p\u003e\n\u003cp\u003eSelank is built from tuftsin, a four-residue immune-active fragment, extended by a three-residue tail to give the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro.\u003c\/p\u003e\n\u003cp\u003eThe extension is the entire design. Tuftsin on its own is cleaved rapidly; adding residues at one end slows that process without altering the original four. It is a clean illustration of a general strategy in peptide chemistry, where stability is engineered by addition rather than substitution.\u003c\/p\u003e\n\u003cp\u003eBecause the parent fragment is itself well characterised, comparisons between the two are unusually informative: any difference in behaviour can be traced to the tail rather than to an unknown structural change.\u003c\/p\u003e\n\u003ch2\u003eKey research areas\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTuftsin-derived sequence research\u003c\/li\u003e\n\u003cli\u003eTerminal extension as a stabilisation strategy\u003c\/li\u003e\n\u003cli\u003eNeuropeptide and monoamine signalling models\u003c\/li\u003e\n\u003cli\u003eParent-fragment comparative studies\u003c\/li\u003e\n\u003cli\u003ePeptide half-life characterisation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e lyophilized powder in a sealed research vial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes available:\u003c\/strong\u003e 5mg, 10mg, and 20mg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack options:\u003c\/strong\u003e 1 vial, 3 vials, or 10 pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular formula:\u003c\/strong\u003e C33H57N11O9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular weight:\u003c\/strong\u003e 751.9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSequence:\u003c\/strong\u003e Thr-Lys-Pro-Arg-Pro-Gly-Pro\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eOther Selank formats and comparable sequences\u003c\/h2\u003e\n\u003cp\u003eSelank is also stocked as a \u003ca href=\"\/products\/selank-nasal-spray\"\u003eSelank nasal spray\u003c\/a\u003e.
