A point of accuracy first: Selank is a synthetic peptide — specifically a heptapeptide made from seven amino acids.
Its sequence is Thr–Lys–Pro–Arg–Pro–Gly–Pro, commonly written as TKPRPGP. Selank is structurally related to tuftsin, a naturally occurring tetrapeptide, with a Pro–Gly–Pro sequence added at the C-terminus.
Supplied as lyophilised Selank at a 10mg nominal fill.

Storage and handling
Store sealed at −20°C for long-term stability, protected from light and moisture. Before opening, allow the vial to equilibrate fully to ambient temperature to reduce condensation and moisture uptake. Reseal promptly and avoid repeated temperature cycling.
Peptide content, residual water and any counterion content should be considered alongside the purity result when preparing quantitative laboratory work.

FAQ
What is Selank?
Selank is a synthetic peptide consisting of seven amino acids with the sequence Thr–Lys–Pro–Arg–Pro–Gly–Pro.
What is a heptapeptide?
A heptapeptide is a peptide formed from seven amino-acid residues joined by peptide bonds.
How is Selank related to tuftsin?
The first four amino acids of Selank reproduce the tuftsin sequence Thr–Lys–Pro–Arg. Selank then adds a Pro–Gly–Pro sequence at the C-terminus.
What is the CAS number for Selank?
129954-34-3.
What is its molecular weight?
751.88 g/mol for the free peptide. The supplied material may include counterions or residual water, so the lot-specific COA should be used for precise calculations.
Is Selank supplied for human use?
No. It is supplied strictly for laboratory research use only and is not for human consumption, medical, veterinary or cosmetic use.
