Selank — Research Guide
Selank is a synthetic heptapeptide analogue of tuftsin developed in Russia as a neuropeptide research compound. It is studied in anxiolytic-pathway, cytokine-modulation, and neuropeptide-receptor research, and is one of the most-cited compounds in modern tuftsin-derivative literature.

Chemistry & identity
Selank (CAS 129954-34-3, MW 751.87 g/mol) has the sequence TKPRPGP — Thr-Lys-Pro-Arg-Pro-Gly-Pro. The C-terminal Pro-Gly-Pro extension distinguishes it from tuftsin (TKPR) and confers extended in-solution stability.
Research applications
- Tuftsin-analogue receptor binding studies
- GABAergic neurotransmission modulation in cell-line and tissue assays
- Cytokine and immune-modulation peptide research
- Intranasal-route bioavailability research models
- Neuropeptide stability and protease-resistance characterization
Stability & storage
Lyophilized Selank is stable at −20°C. The proline residues at the C-terminus contribute to enzymatic stability — Selank is notably more protease-resistant in solution than parent tuftsin.

Adamax — Research Guide
Adamax is a chemically modified Semax analogue incorporating an adamantane moiety. The adamantane modification confers enhanced metabolic stability in published characterizations relative to parent Semax, making it a useful research tool for time-extended neuropeptide assays.
Semax + Selank Blend — Research Guide
The Semax + Selank Blend is a pre-mixed lyophilized cognitive-dual-stack — 10mg of Semax and 10mg of Selank per vial. Both are heptapeptide-class neuropeptide research compounds; the pre-blended format is convenient for combination-research designs targeting both ACTH-derivative and tuftsin-analogue receptor systems.
FAQ
Selank vs Adamax — which is more potent in research?
They target different mechanisms. Selank is a tuftsin analogue acting on neuropeptide-receptor pathways. Adamax is a modified Semax analogue with an adamantane moiety. Selection depends on the assay system. See the Adamax vs Selank comparison page for direct specs.
What's the half-life of free Selank in plasma?
Very short (minutes) in published plasma studies of the free peptide. Intranasal-route bioavailability is the focus of much of the published research because of this short systemic half-life.
What purity does Orion ship?
≥ 99.3% by reversed-phase HPLC, batch-specific value on the COA.
Is this for human use?
No. In-vitro research use only.
