Research context
Selank (CAS 129954-34-3) is a synthetic analog of tuftsin — an endogenous peptide derived from the Fc fragment of IgG. The Pro-Gly-Pro extension distinguishes Selank from tuftsin itself and has been studied in the context of its proteolytic stability profile in laboratory systems.
The scientific literature on tuftsin analogs and Selank examines their receptor-binding pharmacology in in-vitro and preclinical neurobiological research models. Selank has been characterized in published research in the context of neuropeptide pharmacology. It is not approved for human therapeutic use by the FDA or any equivalent regulatory agency.
DMV Research supplies Selank with a per-batch third-party Certificate of Analysis confirming identity and purity for research use.

Frequently asked questions
What is Selank?+
Selank (TP-7) is a synthetic heptapeptide based on the endogenous tuftsin sequence (Thr-Lys-Pro-Arg) with an appended Pro-Gly-Pro tripeptide for metabolic stability. CAS 129954-34-3. Used as a research reference compound.
How does Selank differ from tuftsin?+
Tuftsin is a natural tetrapeptide (Thr-Lys-Pro-Arg) derived from IgG. Selank adds a C-terminal Pro-Gly-Pro sequence that increases its half-life in laboratory systems by slowing enzymatic degradation.
Is Selank approved for human use?+
No. As supplied by DMV Research, Selank is a research chemical for laboratory use only and is not approved for human use by any regulatory agency.
What purity is the Selank research peptide?+
Each batch is independently tested to 99%+ purity by third-party laboratories, with a Certificate of Analysis available per batch.
