SELANK
Compound Overview
Selank is a synthetic heptapeptide developed as a structural analog of the naturally occurring immunomodulatory peptide tuftsin, a tetrapeptide involved in immune system regulation. By extending the tuftsin sequence with three additional amino acids, Selank exhibits enhanced metabolic stability, making it a valuable investigational peptide for studying neurobiology, peptide pharmacology, and neuroimmune interactions.
Researchers continue to investigate Selank in experimental models to better understand its effects on neuropeptide signaling, central nervous system physiology, neurotransmitter regulation, and immune-neural communication. Preclinical studies have examined its influence on GABAergic signaling, monoamine metabolism, cytokine expression, and gene regulation, making it an important tool for investigating molecular pathways involved in neurobiology and peptide-mediated cellular communication.
As an investigational peptide, Selank supports laboratory research involving peptide engineering, pharmacokinetics, neuroendocrine physiology, receptor signaling, and structure-activity relationships.

Product Documentation
Every batch of SELANK is independently tested and assigned its own lot number. When you request documentation, include the product name and lot number printed on your vial so we can send the COA, HPLC, and MS data specific to the batch in your hand — not a generic reference sample.

Laboratory Handling
Store refrigerated immediately upon receipt to preserve peptide stability. For extended laboratory storage, freezing at −20°C or below is recommended. Protect the lyophilized peptide from moisture, excessive heat, and direct light. Avoid repeated freeze-thaw cycles following reconstitution, as these may reduce peptide stability. Allow the vial to equilibrate to room temperature before opening to minimize condensation, and always use sterile laboratory equipment together with appropriate aseptic laboratory techniques. This product is intended for use only by qualified research personnel operating in controlled laboratory environments.
