99% Purity Selank CAS 129954-34-3 Heptapeptide TKPRPGP 5mg 10mg per Vial for Neuropeptide Research

Selank is a synthetic heptapeptide consisting of 7 amino acids with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP). It is a synthetic derivative of the naturally occurring immunomodulatory peptide tuftsin, which is a fragment of the human immunoglobulin G heavy chain . This product is supplied as a lyophilized powder with ≥99% purity (tested by HPLC) .

For laboratory research purposes only. Not for human or veterinary use. Not for diagnostic or therapeutic applications.

Selank is a peptide composed of seven amino acids that has been studied in laboratory research for its interactions with neurotransmitter systems and immune modulation pathways . The peptide is often formulated as an acetate salt for enhanced stability in research settings .

The lyophilized formulation preserves the peptide's structural integrity and bioactivity, allowing for consistent and reproducible results in controlled laboratory settings. Each vial is hermetically sealed to prevent moisture absorption and contamination. The product is intended for in vitro research applications, including cell culture studies, receptor binding assays, and neurochemical analyses.

Key Research Applications: Neuropeptide signaling studies, neurotransmitter pathway research, tuftsin derivative investigations, receptor binding assays, in vitro neurochemical analyses.
