An introduction to Selank, a synthetic tuftsin analog reference material studied in neuropeptide research.
What it is
Selank is a synthetic analog of the peptide tuftsin, supplied strictly as a research-use-only reference material. It is catalogued under the neuropeptide category and identified analytically by CAS number 129954-34-3 and a molecular weight near 751.9 g/mol with a purity specification of not less than 98% by HPLC.
Relationship to tuftsin
Selank is structurally based on tuftsin, a short naturally occurring peptide, extended to improve stability for research use. This relationship places Selank within the tuftsin-analog family and informs the kinds of biological pathways researchers examine when they study the molecule.
