About Selank
Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) designed from the natural immunomodulatory tetrapeptide tuftsin, with an extended chain intended to improve metabolic stability. Its proline-rich structure resists peptidase degradation and gives it distinctive conformational flexibility, which researchers exploit when studying peptide penetration into brain tissue and modulation of central signaling systems. Preclinical work with selank has focused on anxiety-related behavior models, memory and learning paradigms, and the interface between immune mediators and neurotransmission, including effects attributed to changes in monoamine and neurotrophic signaling. Because the peptide is small and heavily proline-based, subtle synthesis artifacts such as incomplete proline coupling, diketopiperazine formation, or isomerized residues can go unnoticed in simple HPLC yet alter biological outcomes. Shandong Shengyuan supplies selank with RP-HPLC purity of 99.8% or higher, verified mass by LC-MS, and full batch documentation. Lyophilized material is offered strictly for research use only; not for human or veterinary use.
