About Selank
Selank is a synthetic heptapeptide developed at the Russian Institute of Molecular Genetics, designed as a stable analog of the endogenous tetrapeptide tuftsin. Its sequence appends a Pro-Gly-Pro tail to the tuftsin core (TKPR) for resistance to enzymatic degradation.
Research interest centers on anxiolytic-pathway models, GABAergic and serotonergic-system interactions, and pre-clinical cognition paradigms. Selank has been the subject of multiple Russian-language publications and Western-translated reviews.
Each lot is independently verified for purity (HPLC + ESI-MS) and endotoxin (LAL kinetic chromogenic) before listing.
