Selank is a synthetic heptapeptide based on the endogenous immunomodulatory tetrapeptide tuftsin (Thr-Lys-Pro-Arg), extended at the C-terminus with a Pro-Gly-Pro tripeptide to improve stability. In research models it is examined for interactions with GABAergic and monoaminergic signalling and modulation of BDNF and enkephalin-degrading enzyme activity.
For laboratory research use only. Not for human or veterinary use.
