Selank is a synthetic heptapeptide analog of the naturally occurring immunomodulatory peptide tuftsin. Developed in Russia, it is widely used in neuroscience as a research tool for studying anxiety-related behavior, cognition, and neuroimmune signaling in laboratory models.
What Is Selank?
Selank is a stabilized analog of tuftsin, a peptide fragment of the immunoglobulin G molecule. The modifications that distinguish Selank from native tuftsin are studied for their effect on peptide stability, making Selank a common model compound in peptide research.
How Selank Is Studied
In published preclinical literature, Selank has been investigated for its relationship to brain-derived neurotrophic factor (BDNF) expression, GABAergic and serotonergic signaling, and the modulation of interleukins and other immune markers. Researchers have also examined its influence on enkephalin-degrading enzymes as a proposed mechanism in anxiolytic research models.
Selank and Semax
Selank is frequently studied alongside Semax, another Russian-developed research peptide, in comparative behavioral models. For a side-by-side look, see our Semax vs. Selank research comparison.
Handling and Reconstitution
Lyophilized Selank is typically kept refrigerated and protected from light for short-term handling and frozen for longer-term storage. See our guide on how to reconstitute a research peptide.
Frequently Asked Questions
What is Selank studied for?
Selank is studied as a tool compound in anxiety-related, cognitive, and neuroimmune research models, particularly in relation to BDNF and immune-marker modulation.
Is Selank the same as Semax?
No. Both are Russian-developed research peptides, but Selank is a tuftsin analog while Semax is an ACTH(4-10) analog. They are often compared in research.
