Selank

Selank is a synthetic heptapeptide based on tuftsin, a naturally occurring tetrapeptide (Thr-Lys-Pro-Arg) found as a fragment of the immunoglobulin G heavy chain. It extends the tuftsin sequence with a Pro-Gly-Pro tripeptide tail. The compound has the molecular formula C33H57N11O9, a weight of 751.87 g/mol, and CAS number 129954-34-3. Also designated TP-7, it is supplied as a white to off-white lyophilized powder, readily soluble in water. Its complete sequence is Thr-Lys-Pro-Arg-Pro-Gly-Pro.

Supplied as one individual 10 mg vial. Each purchase quantity refers to one individual vial, not a supplier box.

Chemical identifiers refer to the stated reference form; salt counterions can change formula weight. Follow the supplied material’s documentation for storage and handling. Cited research is not a batch analysis of this product.
