Application: Species: Mouse

We utilized this product at 1uM to inhibit endothelin-A receptors ex vivo in mouse aortas followed by conducting vasomotor function experiments. We utilized this ET-A inhibitor in combination with Tocris' BQ788 (endothelin-B receptor antagonist) which works equally as well. We have obtained high quality data using this BQ123 product!
