Used in biomedical research to measure 6-keto-prostaglandin F1α levels in biological samples such as plasma, serum, or tissue homogenates. This assay helps assess the in vivo production of prostacyclin, a compound involved in vasodilation and inhibition of platelet aggregation. Commonly applied in studies related to cardiovascular diseases, inflammation, thrombosis, and endothelial function. The kit enables high-throughput, sensitive, and specific quantification, making it valuable in both preclinical and clinical research settings.
