Endothelin 1 (swine, human)

Endothelin-1 (human, swine) is a key vasoconstrictor peptide produced by endothelial cells, signaling via ETA and ETB receptors. It is widely used in research models of hypertension, vascular remodeling, and endothelial dysfunction to study mechanisms of vasoconstriction, oxidative stress, and fibrosis in both in vitro and in vivo settings.
