Selank Research Peptide

Selank is a synthetic analog of the immunomodulatory peptide tuftsin. It has been studied for its potential nootropic and anxiolytic properties in preclinical research.

Selank in Research

Selank is a synthetic heptapeptide analog of tuftsin, the immunomodulatory fragment of immunoglobulin G. Its research literature — largely from the Russian neuropeptide tradition — examines modulation of IL-6 and BDNF expression, monoamine neurotransmitter metabolism, and anxiety-related behavioral endpoints in animal models.

Supplied lyophilized at 5mg and ≥99% purity with batch-specific third-party testing. Researchers comparing regulatory neuropeptides frequently pair Selank with Semax, its ACTH-fragment-derived counterpart from the same research tradition.

Research Overview

  • Studied for modulation of IL-6 and BDNF expression
  • Investigated for effects on monoamine neurotransmitter metabolism
  • Research into anxiolytic-like behavior in rodent models
  • Explored for immunomodulatory properties
  • Preclinical studies on cognitive function enhancement

Quality & Testing

Every Selank batch is verified by independent third-party HPLC and mass-spectrometry testing, with a batch-specific certificate of analysis available on the COA page.

Laboratory Handling & Storage

Lyophilized peptides are supplied as a freeze-dried powder and are most stable stored cold (2–8°C), protected from light and moisture, in the original sealed vial. Under these conditions the research literature generally reports multi-year integrity for dry peptide material.

Once reconstituted in a laboratory setting, solutions are typically stored refrigerated and used within the window appropriate to the diluent and compound; repeated freeze–thaw cycles are avoided because they can promote aggregation. See our research overview on reconstitution and lyophilization for the underlying formulation science.

Frequently Asked Questions

What is Selank?

Selank is a synthetic tuftsin analog (Thr-Lys-Pro-Arg-Pro-Gly-Pro) studied in preclinical models for immunomodulatory and neuromodulatory signaling, including effects on BDNF and monoamine metabolism.

How does Selank relate to Semax?

Both are short regulatory peptides from the same research tradition, but they derive from different parents — Selank from tuftsin, Semax from an ACTH fragment — and are studied for distinct signaling profiles. They are commonly used as comparators.

Is Selank for human use?

No. Selank is supplied strictly for in-vitro and preclinical laboratory research and is not an approved therapeutic in the United States.
