N-Acetyl Selank Amidate is Selank — the tuftsin-derived heptapeptide Thr-Lys-Pro-Arg-Pro-Gly-Pro — with both ends chemically protected. The N-terminus carries an acetyl cap and the C-terminal carboxyl has been turned into a primary amide, so the sequence reads Ac-Thr-Lys-Pro-Arg-Pro-Gly-Pro-NH2. The order of residues stays the same; these are simply the usual ways of guarding a peptide against the amino- and carboxypeptidases that attack free ends.
Peptide Medix EU offers it as a 10 mg lyophilised vial for in vitro assays, analytical method development and authorised animal studies. Every lot is purified by preparative HPLC and identity-checked by mass spectrometry; the certificate of analysis for the lot is available on request. Shipped from our EU warehouse. Not a medicine, supplement or consumer product.

Questions about N-Acetyl Selank Amidate
How is it different from ordinary Selank?
Its sequence is unchanged; what it gains is an acetyl cap at the N-terminus and an amide at the C-terminus, which both stop exopeptidases and cancel the terminal charges. Researchers use it mostly to compare stability and permeability, not because it works by a different mechanism.
Has an independent lab verified the peptide?
Yes — reversed-phase HPLC for purity and mass spectrometry for identity on every lot, with the matching certificate available on request. The measured mass also proves that both end modifications are present in the finished product.
How much material do I receive?
A single 10 mg lyophilised vial — generally enough for a comparative assay series running the protected analogue and unmodified Selank next to each other under identical conditions.
For how long can the dissolved peptide be used?
Refrigerate it at 2–8 °C in the dark and finish it within the period your protocol sets. End-capping slows enzymatic breakdown but doesn't make a peptide stable in water forever, so cold storage and aliquoting remain important.
What solvent suits it?
Bench reconstitution normally uses bacteriostatic water; switch to sterile water when you need a preservative-free preparation. Add the solvent slowly and let the powder dissolve without shaking. Working concentrations are entirely a matter of your assay design.
