Selank Nasal Spray

Selank is a synthetic heptapeptide built on tuftsin — the Thr-Lys-Pro-Arg fragment of the immunoglobulin G heavy chain — extended with a Pro-Gly-Pro terminus that slows enzymatic cleavage relative to tuftsin itself. It is produced by solid-phase synthesis rather than isolated from tissue.

This listing ships the peptide already in solution rather than as a lyophilized powder: 30 mg of Selank in a sterile isotonic saline base, filled to 30 ml in a sealed bottle fitted with a metered atomizing pump rated at roughly 120 actuations. No reconstitution step is involved. Supplied for laboratory research use only.

Published work on Selank sits in preclinical neuropharmacology, where the peptide is used as a probe for signaling questions. Reported areas of study include:

• Tuftsin-receptor and immunomodulatory signaling — whether the parent fragment interaction with immune-cell receptors carries over to the extended analog.
• Monoamine and GABAergic pathways — measured shifts in neurotransmitter turnover in rodent models.
• BDNF and gene-expression readouts in hippocampal tissue.
• Enzymatic stability — comparative degradation of the Pro-Gly-Pro-extended sequence against native tuftsin.

This literature is animal-model and in vitro. Elements DNA makes no outcome claim for this compound and supplies it as a characterized reagent.
