Selank

Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) structurally derived from the endogenous immunomodulatory peptide tuftsin, extended with a stabilizing terminal sequence intended to improve resistance to enzymatic degradation. As a short, water-soluble regulatory peptide, it belongs to the broader class of neuropeptide analogs widely referenced as tool compounds in preclinical and in-vitro study systems. Pet & Peps Research supplies Selank as a lyophilized powder at >=99% HPLC purity, characterized for identity and intended strictly as a laboratory reference material.

Within companion-animal research programs, Selank is investigated for its role in neuropeptide signaling pathways. Laboratory studies of tuftsin-derived peptides have examined receptor-level interactions and downstream signaling cascades, positioning Selank as a useful reference compound for investigators characterizing peptidergic mechanisms in canine and feline cell-based and tissue models. It is frequently referenced in exploratory work mapping how short regulatory peptides interact with biological signaling systems under controlled laboratory conditions.

Selank is additionally of research interest in anxiety-model research and immune-modulation research, where it serves as a comparator peptide for investigators designing controlled studies. Owing to its structural relationship to tuftsin, it is studied in laboratory immunology models exploring peptide-associated modulation of immune signaling. Across all of these contexts Selank is positioned solely as an investigational reference compound for characterizing biological pathways in study models relevant to companion animals — never as a therapeutic.
