Selank is a synthetic heptapeptide originally developed for neuroscience and neuroimmunology laboratory studies. It was designed based on the sequence of endogenous tuftsin, with structural modification to improve metabolic stability and biological activity in preclinical models. Unlike many traditional small-molecule neuroactive compounds, Selank demonstrates dual regulatory effects on the nervous system and immune system, making it a popular research tool for exploring neuroendocrine signaling pathways.

In preclinical research, Selank is studied for its ability to modulate multiple neurotransmitter systems including serotonin, dopamine and GABA. Laboratory observations indicate that this peptide can participate in the regulation of stress response pathways, affect the expression of inflammatory cytokines, and exert balancing effects on immune cell functions. A large volume of in vitro and animal model research focuses on its impacts on cognitive function, learning and memory processes, as well as the body’s adaptive reaction to chronic stress.

The product is manufactured using solid-phase peptide synthesis technology. After synthesis, crude peptide is purified by preparative high-performance liquid chromatography, then sterile filtered and lyophilized into dry powder form. Lyophilization effectively slows down peptide degradation and maintains batch-to-batch consistency. Every production batch undergoes comprehensive QC tests, including HPLC purity analysis, MS identification, residual moisture testing and endotoxin assay to meet standards for in vitro cell experiments and animal research. The peptide is relatively stable under recommended storage conditions, yet prolonged exposure to room temperature, strong light or high humidity will accelerate degradation.
