Selank Research Reference
A documentation-focused reference page for Selank as a research compound. It describes the material, its research context, how purity and identity are verified, and how it is stored and handled in the lab. No effects are claimed. Supplied for research use only.
What it is
Selank (also designated TP-7) is a synthetic peptide developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It is a synthetic analog of the endogenous immunomodulatory peptide tuftsin, with an additional Gly-Pro sequence. As a research compound it is supplied as a lyophilized powder.
Research context
Selank is referenced in laboratory neuroscience research, where it is studied alongside related synthetic peptides such as Semax. This page notes only that Selank is a referenced compound in published research; it makes no claim about any effect. A purity-verified reference material provides a defined, characterized compound for study in these contexts.
How purity is verified
The material is characterized per lot:
- HPLC for purity, read with the chromatogram; research-grade material is ≥99% by reverse-phase HPLC.
- Mass spectrometry for identity, matching the observed mass to the theoretical mass.
- LAL (Limulus Amebocyte Lysate) for bacterial endotoxin, commonly referenced to USP <85>.
All three results are documented on a lot-matched certificate tied to the lot number on the vial. Material is synthesized in the USA.
Storage and handling for lab use
General laboratory handling notes for lyophilized Selank:
- Lyophilized powder. Store at -20°C. Keep the vial sealed and dry until ready to reconstitute.
- Reconstitution. Bacteriostatic water is the most commonly referenced solvent. Add slowly along the vial wall and swirl gently.
- Reconstituted solution. Commonly refrigerated at 2-8°C. Selank is referenced as stable in solution at pH 5-7 and maintaining potency for several weeks at about 4°C after reconstitution. Avoid repeated freeze-thaw cycles.
Exact parameters depend on your protocol and the requirements of the work.

What is Selank?
Selank (TP-7) is a synthetic peptide developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It is a synthetic analog of the immunomodulatory peptide tuftsin with an added Gly-Pro sequence, supplied as a lyophilized powder for research use.
How is Selank related to tuftsin?
Selank is a synthetic analog of the endogenous peptide tuftsin, with an additional Gly-Pro sequence relative to the tuftsin structure.
How is Selank purity verified?
Per lot, using reverse-phase HPLC for purity (≥99% research-grade), mass spectrometry for identity, and the LAL assay for endotoxin, all documented on a lot-matched certificate of analysis.
How should Selank be stored?
As a lyophilized powder at -20°C, kept sealed and dry until reconstitution. Reconstituted solution is commonly refrigerated at 2-8°C, referenced as stable for several weeks at around 4°C at pH 5-7, with freeze-thaw cycles avoided.
Is research Selank for human use?
No. It is supplied for research use only, as a characterized laboratory reference compound, not for human, veterinary, or diagnostic use. ## Related pages - Selank product page and lot COA - What "research use only" means - Browse the research catalog
