Selank is a synthetic heptapeptide (CAS 129954‑34‑3) with ≥99% purity, developed as a tuftsin analogue for anxiolytic, nootropic, and immunomodulatory research. It is supplied as a lyophilized powder or diacetate salt, stored at −20 °C, and reconstituted for in‑vitro use only.

KEY FEATURES 

Anxiolytic properties: Reduces anxiety without sedation or dependency.

Nootropic effects: Enhances focus, memory, and learning.

Immunomodulation: Influences cytokine balance and immune regulation.

Neuroprotection: Elevates BDNF and stabilizes neurotransmitter systems.

Tuftsin analogue: Extends natural tetrapeptide Thr‑Lys‑Pro‑Arg with Pro‑Gly‑Pro for stability.
