Elabela (19-32) (TFA)

Elabela (19-32) TFA is an active fragment of ELABELA (ELA) that binds to apelin receptor (APJ) . Elabela (19-32) TFA activates the Gαi1 and β-arrestin-2 signaling pathways with EC50s of 8.6 nM and 166 nM. Elabela (19-32) TFA induces receptor internalization and reduces arterial pressure, exerts positive inotropic effects on the heart[1].
