Selank

Selank is a seven-amino-acid peptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, abbreviated TKPRPGP. QURE lists Selank as an individual 10mg research product. Its compact sequence places it among heptapeptides, alongside other seven-residue compounds with different molecular identities.

The opening four residues are followed by a Pro-Gly-Pro segment. This sequence arrangement provides a specific identifier for comparing chemical references and distinguishes Selank from materials that merely share a similar name or chain length. A matching residue count alone does not identify the same peptide.

Semax is another heptapeptide in the QURE catalog, but its first four residues differ from those of Selank. The two share a terminal sequence segment without being interchangeable compounds. Their individual listings should remain separate in purchasing records and scientific documentation.

Published analytical work has examined Selank’s sequence and peptide degradation. Such studies describe a research subject; they do not verify the composition or purity of a particular commercial lot. The listed 10mg is a product quantity rather than a claim about experimental performance.
