Selank Nasal Spray 5 mg

Selank Nasal Spray for research: identity and specifications

Selank (also catalogued as a tuftsin analog, Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a synthetic heptapeptide derived from the endogenous tetrapeptide tuftsin. This presentation is a ready-to-use atomized solution in a 10 mL metered-pump spray bottle containing 5 mg of peptide at a concentration of 0.5 mg/mL (CAS 129954-34-3), with the lot-specific HPLC purity reported on the certificate of analysis.

Scientific background

Selank extends the tuftsin core (Thr-Lys-Pro-Arg) with a Pro-Gly-Pro tail designed to slow enzymatic degradation. In experimental models it is investigated for tuftsin-derived neuropeptide signaling, for interaction with GABAergic pathways and for effects on enkephalin breakdown.

The atomized liquid format is used in research on intranasal peptide absorption and bioavailability in experimental models, where standardized dispensing of a defined solution is needed. These are observations from preclinical and in vitro systems, always under controlled bench conditions and without extrapolating results to human or veterinary use.

• Intranasal peptide absorption and bioavailability in experimental models
• Tuftsin-derived neuropeptide signaling
• GABAergic pathway modulation in experimental models
• Peptide stability and enkephalin degradation assays

Technical specifications

Analytical quality and chain of custody

Every lot of Selank is synthesized in registered facilities, with independent analytical verification by third-party laboratories and full chain-of-custody documentation. The certificate of analysis (COA) for each lot can be reviewed before purchase, recording HPLC purity and the other quality-control parameters used to release the material.

Laboratory handling

Because the product is a ready-to-use solution, there is no reconstitution step. As a bench procedure, keep the metered-pump bottle sealed and protected from light between uses, store it as indicated above, and dispense only in a controlled laboratory environment to preserve the 0.5 mg/mL concentration. Handling must be performed only by qualified personnel, in a bench environment suitable for in vitro experimentation, with lot number and storage conditions documented according to good laboratory practice.

Frequently asked questions

What is the purity of the Selank supplied?

≥98% by HPLC, with the lot-specific value reported on the certificate of analysis (COA).

Why a liquid spray instead of a lyophilized powder?

The atomized solution is used in research on intranasal peptide absorption, where a ready-made, defined-concentration liquid in a metered-pump bottle allows standardized dispensing and removes the reconstitution step.

How should the product be stored?

At -20 °C, protected from light and moisture, in the original sealed container.

Does the certificate of analysis come with the lot?

Yes, every lot has a matching COA that can be verified before purchase using the button on this page.

Who can purchase Selank Nasal Spray?
