{"product_id":"selank-fe","title":"Selank Fe","description":"\u003cp\u003e\u003cspan\u003eSelank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) derived from the endogenous immunomodulatory peptide tuftsin (Thr-Lys-Pro-Arg) with a Pro-Gly-Pro C-terminal extension for enhanced stability. Developed at the Institute of Molecular Genetics, Russian Academy of Sciences — the same laboratory that created Semax — Selank is structurally complementary to Semax but acts through distinct receptor pathways.Laboratory research has investigated Selank's modulation of enkephalinase activity and its effects on endogenous opioid peptide metabolism (Met-enkephalin, Leu-enkephalin). In-vitro studies have examined its interaction with GABAergic neurotransmission, specifically GABA-A receptor complex modulation. Research has also explored its effects on monoamine neurotransmitter balance (serotonin, dopamine, norepinephrine), IL-6 expression in immune cell models, and BDNF\/trkB signaling pathways in neuronal cultures.Molecular Weight: 751.88 g\/mol. Sequence: TKPRPGP. Appearance: White lyophilized powder. Solubility: Soluble in water. Storage: -20°C, lyophilized, sealed and protected from light.\u003c\/span\u003e\u003c\/p\u003e","brand":"True Peptides","offers":[{"title":"10mg","offer_id":50579922157638,"sku":null,"price":45.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/6781\/4470\/files\/2026-10-07_160751_490.png?v=1791428776","url":"https:\/\/true-peptokes.shop\/products\/selank-fe","provider":"True Peptides","version":"1.0","type":"link"}
