Used in biomedical research to measure levels of 6-keto-prostaglandin F1α in biological samples such as plasma, serum, or cell culture supernatants. This compound is a stable metabolite of prostacyclin (PGI2), which is involved in vasodilation and inhibition of platelet aggregation. The ELISA kit enables researchers to assess endothelial function and monitor conditions related to vascular inflammation, thrombosis, and cardiovascular diseases. It is widely applied in studies of atherosclerosis, diabetes, hypertension, and drug development targeting the prostaglandin pathway. The assay provides a sensitive and specific quantitative analysis, supporting both clinical research and preclinical investigations.
