N-Acetyl Selank Research Peptide — Scientific Overview
N-Acetyl Selank is a modified form of Selank — the synthetic heptapeptide derived from the human tuftsin immunomodulatory peptide sequence — in which an acetyl group is added to the N-terminus. Like the N-acetylation approach applied to Semax, this modification protects Selank against aminopeptidase degradation, extending the peptide’s effective duration in biological research systems. Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) was developed at the Institute of Molecular Genetics of the Russian Academy of Sciences as a synthetic tuftsin analog with anxiolytic and nootropic properties.

N-Acetyl Selank’s research profile overlaps with native Selank — anxiolytic effects without sedation, immune system modulation, cognitive-enhancing properties, and interactions with the GABAergic system — but with extended duration of action due to improved aminopeptidase resistance. Research has documented that N-Acetyl Selank produces anxiolytic and immunomodulatory effects that are more sustained than equivalent doses of native Selank, making it useful for longer-duration research models.

Storage & Handling (Research Laboratories)
Lyophilized N-Acetyl Selank should be stored at −20°C for long-term preservation, protected from light and moisture. For short-term active research use, 4°C storage is acceptable for up to approximately 4 weeks. Minimize repeated freeze-thaw cycles. Follow standard laboratory peptide reconstitution and handling protocols for all experimental use.
