Endothelin 1 (swine, human), Alexa Fluor 488-labeled is an Endothelin-1 conjugated with Alexa Fluor 488 (HY-D1304). Endothelin-1 is an endogenous vasoconstrictor and agonist of ETA/ETB receptor. Endothelin 1 (swine, human) exerts effects including promoting mitosis, angiogenesis, tumor invasion and metastasis, and inhibiting apoptosis. Endothelin 1 (swine, human) induces inflammation and oxidative stress by activating the NF-κB pathway. Endothelin 1 (swine, human), Alexa Fluor 488-labeled is specifically designed for fluorescence imaging, flow cytometry or receptor localization studies, and can be used in research related to sepsis, atherosclerosis, systemic inflammatory response syndrome, cancer and congestive heart failure.
