Used in biomedical research to measure prostacyclin (PGI2) levels in biological samples such as plasma, serum, or tissue homogenates. This ELISA kit enables researchers to quantify PGI2 metabolites, which are indicators of endothelial function and vascular health. It is commonly applied in studies related to cardiovascular diseases, inflammation, thrombosis, and atherosclerosis. The assay supports investigation into drug effects, especially those involving cyclooxygenase pathways or anticoagulant therapies. Due to its high sensitivity and specificity, it is valuable in preclinical studies using rat models to assess vascular and metabolic responses.
