ELA-21 (human)New
Biological Activity
High affinity apelin receptor agonist. Binds apelin receptors in left ventricle from normal and pulmonary arterial hypertensive (PAH) hearts (pKi values are 9.31 and 9.46, respectively). Bioactive fragment of ELA-32 (Cat. No. 6291). Inhibits forskolin-induced cAMP production and stimulates β-arrestin recruitment in vitro.
