Description: Potent and high affinity apelin agonist; stimulates angiogenesis
Alternative Names: APJ early endogenous ligand,Apela,Elabela,Toddler
Biological Activity for ELA-32 (human)
ELA-32 (human) is a potent, high affinity apelin receptor agonist (IC50 = 0.27 nM; Kd = 0.51 nM). Exhibits no binding GPR15 and GPR25. Activates the PI3K/AKT pathway and promotes self-renewal of hESCs via cell-cycle progression and protein translation. Also potentiates the TGFβ pathway, priming hESCs toward the endoderm lineage. Stimulates angiogenesis in HUVEC cells. Relaxes mouse aortic vessels. Functions as an anorexigenic hormone through activation of the AVP and CRH neurons in the PVN.
Negative control (Cat.No. 6292) also available.
