Frequently Asked Questions
What is Selank in research contexts?
+
Selank is a synthetic heptapeptide derived from the natural immunomodulatory tetrapeptide tuftsin and developed in Russian neuropeptide research. It is studied in preclinical models for anxiolytic effects, GABAergic modulation, BDNF expression, and immunomodulatory activity.
What should researchers verify when sourcing Selank?
+
Verify HPLC purity above 98%, mass spec identity confirming the seven-amino-acid sequence (Thr-Lys-Pro-Arg-Pro-Gly-Pro), peptide content quantification, endotoxin testing, and a recent batch-specific COA. Stability data is essential for the lyophilized form.
Where can research labs source verified Selank?
+
Midwest Peptide supplies research-grade Selank with comprehensive COA documentation, HPLC purity verification, mass spec identity confirmation of the heptapeptide sequence, and lot tracking for reproducible neuropeptide research.
Is Selank approved for human use?
+
No. Selank is not approved by the FDA for any human therapeutic use. It is supplied strictly for in-vitro and preclinical research purposes by qualified investigators.
Glossary
Key terms used in this article.
- Tuftsin
- An endogenous tetrapeptide (Thr-Lys-Pro-Arg) liberated from the Fc domain of immunoglobulin G, the structural basis for Selank.
- GABAergic
- Pertaining to neurons, synapses, or signaling pathways using gamma-aminobutyric acid (GABA), the primary inhibitory neurotransmitter.
- Anxiolytic
- Pertaining to compounds that reduce anxiety in behavioral or physiological studies.
- BDNF
- Brain-derived neurotrophic factor, a key neurotrophin supporting neuronal survival, synaptic plasticity, and learning.
- Heptapeptide
- A peptide consisting of seven amino acid residues; both Selank and Semax are heptapeptides.
- Synthetic Heptapeptide
- A peptide consisting of seven amino acid residues produced by chemical synthesis, the format of both Selank and Semax.
- Sequence Verification
- Analytical confirmation that a peptide matches its expected amino acid sequence, typically by mass spectrometry.
