§ PP-005Tuftsin analogue

Selank

Tuftsin-Derived Heptapeptide

Tuftsin analogue. Stored at −20 °C; thaw once only. Selank is a short tuftsin analogue presented as a freeze-dried solid with amber-glass packaging and argon-flushed headspace.

Synthesis uses Fmoc solid-phase chemistry with HBTU activation; crude peptide is precipitated in cold ether and polished by reverse-phase HPLC until purity floors at 99.24%. Every lot leaves the bench with ESI-TOF, LAL endotoxin, and residual-solvent data attached.

Lyophilised material is stable frozen at −20 °C. In aqueous solution, HPLC purity holds refrigerated for roughly two weeks; single-thaw only, no repeated freeze-thaw cycles.
