Used in biomedical research to measure prostacyclin levels in biological samples such as plasma, serum, or cell culture supernatants. Prostacyclin is a potent vasodilator and inhibitor of platelet aggregation, so this kit is valuable in studies related to cardiovascular health, thrombosis, inflammation, and endothelial function. Researchers use it to assess the activity of the cyclooxygenase pathway, evaluate drug effects on prostaglandin production, and investigate diseases involving vascular dysfunction, such as hypertension, atherosclerosis, and pulmonary arterial hypertension. The ELISA format allows for sensitive and specific quantification, making it suitable for both basic research and preclinical studies.
