Selank Spray (5MG)

Selank in pre-reconstituted intranasal spray format — the same tuftsin-analog signaling research peptide as our 5mg lyophilized standard, supplied in a metered-dose vial for laboratory protocols where on-site reconstitution is impractical.

Format rationale

Intranasal-format references streamline workflows when Selank is screened alongside other signaling-peptide research compounds. The spray retains the same 7-residue Fmoc-SPPS-synthesized heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) as the lyophilized standard, pre-dissolved in a pH-buffered isotonic vehicle.

Synthesis & verification

The active heptapeptide is produced by solid-phase peptide synthesis using Fmoc protecting-group strategy in a U.S.-based ISO 9001:2008 facility, then verified post-formulation for identity (LC-MS), purity (reverse-phase HPLC-UV ≥99.0%), and concentration. Each lot ships with its signed Certificate of Analysis.

Storage & handling

Pre-reconstituted vials remain stable at 2-8 °C in original packaging for the printed shelf life. Protect from light, avoid freeze-thaw, and store upright. The peptide is robust under typical handling conditions.

Why BioFusion

Spray-format peptide references can drift if not formulated with internal stability data. BioFusion’s spray vials are verified at formulation and re-verified at release. Batch transparency ledger shows every released lot. Bulk discounts at three+; members save 25% plus complimentary U.S. shipping for 365 days.
