Description

Selank is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, molecular formula C₃₃H₅₇N₁₁O₉, a molecular weight of approximately 751.87 Da, and CAS number 129954-34-3. Selank is a chimeric peptide combining the tuftsin (Thr-Lys-Pro-Arg) receptor binding tetrapeptide with a stabilizing Pro-Gly-Pro C-terminal extension derived from the ACTH fragment design strategy.

In laboratory research, Selank is utilized in GABAergic neurotransmission modulation studies (GABA-A receptor subunit gene expression profiling), monoamine neurotransmitter metabolism investigations (serotonin, dopamine, norepinephrine turnover), enkephalinase inhibition assays, IL-6 and TNF-α cytokine production experiments, T-cell and macrophage immune function assays, and receptor binding signaling mechanism investigations in behavioral neuroscience models.

Supplied as a lyophilized powder with ≥99% purity verified by HPLC. For storage and handling conditions, refer to the Certificate of Analysis provided with each lot. This product is intended strictly for laboratory research use only (RUO) and is not for human consumption, therapeutic use, or any diagnostic purposes.
