Compound Overview

About Selank

Selank is a synthetic tuftsin analog research peptide studied for anxiety-related signaling, GABAergic modulation, and immune-neural interaction in preclinical neuroscience models.

Selank is a heptapeptide research compound built from the immunomodulatory peptide tuftsin with a stabilizing Pro-Gly-Pro extension. Developed alongside Semax in Russian research institutes, it is examined in preclinical studies of anxiety-related behavior, GABA and monoamine neurotransmission, and the interface between immune signaling and the nervous system.

Research Applications

  • Anxiety-related behavioral models in preclinical research
  • GABAergic and monoamine neurotransmission studies
  • Neuroimmune signaling research
  • Tuftsin analog structure-activity studies

Handling & Storage

Supplied as a lyophilized powder. Store sealed vials in a cool, dry place away from light; refrigerate after reconstitution with bacteriostatic water and avoid repeated freeze-thaw cycles.

This compound is intended for in-vitro research and laboratory use only. Not for human consumption.
