Product Overview

Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) derived from tuftsin, a naturally occurring tetrapeptide (Thr-Lys-Pro-Arg) fragment of immunoglobulin G. Selank serves as a biological research tool for investigating neuropeptide receptor signaling pathways, GABAergic system modulation, and enzyme inhibition kinetics in controlled laboratory settings.

Supplied as a lyophilized research reagent at ≥99% purity. Every order is accompanied by an independent third-party verified Certificate of Analysis with a unique authentication key for direct lab verification.

Research Applications

Selank is intended for use in qualified laboratory research environments, including:

  • Neuropeptide receptor signaling and GABAergic pathway modulation research
  • Enkephalin-degrading enzyme inhibition kinetics and characterization
  • Gene expression profiling in neuronal cell models
  • GABA receptor allosteric modulation and binding studies
  • Peptide-based enzyme inhibitor pharmacology and SAR research

Mechanism of Action

Selank is a synthetic heptapeptide and analogue of tuftsin (Thr-Lys-Pro-Arg), a naturally occurring tetrapeptide fragment of immunoglobulin G. Research indicates that Selank modulates the GABAergic signaling pathway, where it acts as a positive allosteric modulator of GABA binding at GABA-A receptors. Selank also inhibits enkephalin-degrading enzymes (enkephalinases), with an IC₅₀ of approximately 20 μM. Additionally, Selank influences the expression of genes involved in neurotransmission in neuronal cell models. These molecular activities make Selank a research tool for studying neuropeptide receptor pharmacology and enzyme inhibition mechanisms.

Frequently Asked Questions

What is Selank?

Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) derived from tuftsin, a naturally occurring tetrapeptide fragment of immunoglobulin G. It serves as a research tool for studying neuropeptide receptor signaling, GABAergic pathway modulation, and enkephalin-degrading enzyme inhibition.

What is the CAS number for Selank?

The CAS registry number for Selank is 129954-34-3.

What is the amino acid sequence of Selank?

Selank is a heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro (single-letter code: TKPRPGP). It is a synthetic analogue of tuftsin (Thr-Lys-Pro-Arg), extended with Pro-Gly-Pro at the C-terminus.

What is tuftsin?

Tuftsin (Thr-Lys-Pro-Arg) is a naturally occurring tetrapeptide derived from the Fc region of immunoglobulin G. It plays a role in immune cell signaling. Selank was designed as a tuftsin analogue to study neuropeptide receptor signaling and enzyme inhibition pathways.

How should Selank be stored?

Store the lyophilized material at -20°C upon receipt. Protect from moisture and direct light. Allow the vial to equilibrate to room temperature before opening.

Is a Certificate of Analysis included?

Yes. Every order includes a batch-specific Certificate of Analysis with an independent third-party verification key, verifiable directly through the testing laboratory’s online portal.
