What is Selank?

Selank is a synthetic heptapeptide analog based on the immunomodulatory peptide tuftsin, developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It consists of the tuftsin sequence (Thr-Lys-Pro-Arg) with an added Pro-Gly-Pro stabilizing sequence.

Research has focused on Selank's interactions with GABAergic, serotonergic, and dopaminergic neurotransmitter systems. Published studies have examined its effects on gene expression related to BDNF and enkephalin pathways in animal models.

Manufactured under cGMP-equivalent protocols and verified to ≥99% purity via HPLC. Full COA included with every order.

Supplied as a lyophilized white powder. Soluble in sterile water. For research and laboratory use only.
