Selank is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, derived as an analogue of the immunomodulatory tetrapeptide tuftsin. Supplied as a ready-to-use 10mg/10ml nasal spray solution, this format provides a convenient vehicle for research protocols requiring intranasal peptide delivery models.
Specifications: Dose: 10mg | Volume: 10ml | Format: Nasal spray | Purity ≥99% | Peptide sequence: Thr-Lys-Pro-Arg-Pro-Gly-Pro | CAS: 129954-34-3
Research context: studied in experimental systems for investigation of GABA-A receptor modulation, anxiolytic pathway research, and innate immune system interactions. For in-vitro and laboratory research use only.
Research Background
This Selank nasal spray presents the synthetic heptapeptide Thr-Lys-Pro-Arg-Pro-Gly-Pro (MW 751.87 Da, CAS 129954-34-3) in a preserved 10ml aqueous solution at 1mg/ml concentration. The ready-to-use spray format eliminates reconstitution steps, providing researchers with a pre-prepared solution optimised for intranasal delivery model studies, olfactory epithelium permeability assays, and rapid-administration ex-vivo research protocols.
The stability of Selank in preserved aqueous solution has been characterised in studies examining the peptide’s enhanced resistance to dipeptidyl peptidase IV (DPP-IV) and other serine proteases — attributed to its C-terminal Pro-Gly-Pro extension. Research has employed this format in studies of transmucosal peptide transport, olfactory receptor neuron (ORN) exposure models, and in-vitro BBB permeability assays.
