Selank is a synthetic tuftsin-derived heptapeptide with the reference sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. Its reference molecular formula is C33H57N11O9 and its molecular weight is 751.87 g/mol. The peptide is widely used in neurobiology, stress-response, peptide-signaling, and neuroimmune research because its short, defined sequence is suitable for controlled pathway studies and comparative work with tuftsin-related fragments.

Selank is positioned as a research peptide for laboratories and R&D organizations seeking a practical reagent for neurotransmission-related and neuroimmune models. It can be incorporated into biochemical assays, cell studies, gene-expression projects, and comparative model development. The material is supplied for laboratory research and analytical use only, with actual purity, salt form, content basis, and storage conditions stated in the lot documentation.

Mechanism of Action

Selank has been studied in relation to GABA-associated signaling, receptor-linked responses, and the expression of genes involved in neurotransmission. Research suggests that its effects may extend beyond a single receptor and may involve coordinated changes in peptide metabolism, intracellular signaling, and neural-immune communication.

Its tuftsin-derived structure also supports studies of peptidase activity and short regulatory peptide networks. Researchers may compare Selank with tuftsin, related fragments, vehicle controls, or pathway-specific controls to clarify sequence-dependent activity. Responses remain model- and time-dependent, making controlled study design essential.

Research Value

Selank provides a compact peptide tool for connecting molecular readouts with broader neural and stress-response models. It can support transcript analysis, receptor-pathway studies, peptidase assays, cytokine panels, electrophysiological work, and behavioral research designs where the aim is to compare mechanisms rather than assume a predetermined result.

It s clear sequence, manageable molecular size, and broad compatibility with neurobiology workflows make it attractive for exploratory programs, method development, reference-material studies, and analog screening. Reliable batch documentation is particularly valuable where multiple experiments must be compared over time.
