Neuropeptides
Selank research peptide
Selank is a synthetic heptapeptide built on tuftsin, a naturally occurring tetrapeptide (Thr-Lys-Pro-Arg), extended with a C-terminal Pro-Gly-Pro sequence intended to improve stability against peptidases. It was developed at the Institute of Molecular Genetics of the Russian Academy of Sciences.
For in-vitro laboratory research only. Not for human or veterinary use.

|---|---|---|
| Purity | HPLC-UV | ≥ 99.0% |
| Net peptide content | Quantitative HPLC | ≥ 100% of label |
| Identity | LC-MS | Matches theoretical mass |
| Appearance | Visual | White lyophilized cake |
| Fentanyl screen | LC-MS/MS | Not detected |

| Endotoxin | LAL | Within specification |
Frequently asked questions
What is Selank?
Selank is a synthetic heptapeptide built on tuftsin, a naturally occurring tetrapeptide (Thr-Lys-Pro-Arg), extended with a C-terminal Pro-Gly-Pro sequence intended to improve stability against peptidases. It was developed at the Institute of Molecular Genetics of the Russian Academy of Sciences.
How is each Selank lot tested?
Every lot is tested at an ISO/IEC 17025 accredited third-party laboratory against an eight-assay panel: HPLC-UV purity, quantitative net peptide content, LC-MS identity, appearance, a fentanyl screen, heavy metals by ICP-MS, sterility by PCR, and endotoxin by LAL. The certificate is published before the lot ships.
How do I verify the certificate for my Selank vial?
Scan the QR code on the vial label to open the certificate for that exact lot, or search the lot number in the North Wall COA library.
Is Selank for human use?
No. North Wall sells this compound solely for in-vitro laboratory research by qualified researchers aged 21 and over. It is not for human or veterinary use, and North Wall does not provide use, preparation, or dosing guidance.
