Selank is a synthetic heptapeptide based on the tuftsin sequence with a threonine-lysine-proline-arginine-proline-glycine-proline structure, investigated for anxiolytic, immunomodulatory and cognitive effects in animal models. Its dual influence on anxiety behavior and immune parameters distinguishes it in neuropeptide research. The material is a white lyophilized powder at >=99% HPLC purity in a sealed vial. We offer batch documentation, flexible pack sizes and fast international delivery for research programs. The peptide content is verified before release, and each batch is assigned a unique reference for traceability. Whether you need a single vial for a pilot experiment or kilograms for a long program, our production capacity and export experience can match the requirement with stable lead times.
