About Selank
Selank consists of tuftsin, the immunomodulatory tetrapeptide Thr-Lys-Pro-Arg from the heavy chain of immunoglobulin G, extended with Pro-Gly-Pro at the C-terminus. The Pro-Gly-Pro addition slows enzymatic breakdown, the same strategy used in Semax.
It was developed at the Institute of Molecular Genetics of the Russian Academy of Sciences, which also developed Semax.
Research context
Selank is studied in research on neuropeptide modulation of behavior in rodent models, GABAergic signaling, monoamine and BDNF expression and immune-related gene expression. Most of the literature comes from Russian research groups.

Selank: frequently asked questions
How is Selank different from Semax?
Both use the Pro-Gly-Pro stabilizing extension, but they are built on different parent peptides: Selank on tuftsin, Semax on the ACTH 4-7 fragment.
Which Selank presentations are listed?
2 presentations are listed: 5 mg (SK5), 10 mg (SK10). Each is packed 10 vials per box, and every presentation has its own specification page and product code.
