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. Quality control includes HPLC assay, peptide-content verification and moisture testing before release, with results shared per batch. Buyers may request custom vial sizes, private labeling and combined shipping of multiple products, and we maintain stock for fast dispatch of popular items. Technical consultation on storage and handling is included with every order.
