The apelin gene encodes a pre-proprotein that is processed to generate bioactive peptides consisting of 36, 17, or 13 amino acids: apelin-36 (Item No. 13524), apelin-17, and apelin-13 (Item No. 13523), respectively. Apelin-13 is an endogenous ligand of the APJ receptor, activating this G protein-coupled receptor with an EC50 value of 0.37 nM.1,2 (Glp1)-Apelin-13 is a pyroglutamylated form of apelin-13, in that the N-terminal glutamine residue is cyclized to pyroglutamic acid. Like apelin-13, this compound is a potent APJ receptor agonist (EC50 = 0.30 nM).1 (Glp1)-Apelin-13 is the major apelin isoform in the plasma of healthy human subjects.3 It can have vasoconstrictor and antipyretic effects in vitro and in vivo.4,5,6WARNING This product is not for human or veterinary use.
