Selank, also known as TP?7, CAS 129954?34?3, is a synthetic heptapeptide analog derived from tuftsin. Amino?acid sequence: Thr?Lys?Pro?Arg?Pro?Gly?Pro (TKPRPGP), molecular formula C??H??N??O?, molecular weight 751.87 g/mol. It is supplied as white to off?white lyophilized powder with HPLC purity ≥98%. Extended by Pro?Gly?Pro fragment at C?terminal, Selank obtains improved metabolic stability compared with native tuftsin.
Produced by solid?phase peptide synthesis and RP?HPLC purification. Each batch is strictly tested by HPLC, mass spectrum identification and endotoxin detection. Our Selank peptide features low endotoxin, stable batch?to?batch performance and excellent water?solubility, which meets international research?grade peptide standards.
