Research profile & documentation
- Why researchers study it
- Studied in vitro as a synthetic tuftsin-analog probe for investigating GABAergic and immunomodulatory signaling pathways relevant to central-nervous-system research.
- Mechanism themes in research
- GABA-A receptor-adjacent signaling pathway studiesTuftsin-analog immunomodulatory structure-activity chemistryEnzymatic-stability modifications (Pro-Gly-Pro tail) extending in-vitro half-lifeAnalytical reference standard for identity and purity (HPLC/MS)
- What the evidence does not establish
- Published references are in-vitro or pre-clinical and describe research context only. They do not establish safety, efficacy, or any outcome in humans or animals, and Helix makes no such claims.

An introduction to Selank, a synthetic tuftsin analog reference material studied in neuropeptide research.
What it is
Selank is a synthetic analog of the peptide tuftsin, supplied strictly as a research-use-only reference material. It is catalogued under the neuropeptide category and identified analytically by CAS number 129954-34-3 and a molecular weight near 751.9 g/mol with a purity specification of not less than 98% by HPLC.
Relationship to tuftsin
Selank is structurally based on tuftsin, a short naturally occurring peptide, extended to improve stability for research use. This relationship places Selank within the tuftsin-analog family and informs the kinds of biological pathways researchers examine when they study the molecule.
