Used in biomedical research to quantify levels of prostaglandin-endoperoxide synthase 2 (PTGS2), also known as cyclooxygenase-2 (COX-2), in biological samples such as cell lysates, serum, plasma, and tissue homogenates. This ELISA kit enables researchers to study inflammation, immune responses, and cancer progression, as PTGS2 is upregulated in inflammatory conditions and various tumors. It is widely applied in drug development to assess the efficacy of anti-inflammatory agents, including NSAIDs and selective COX-2 inhibitors. The assay provides high sensitivity and specificity, allowing accurate measurement of PTGS2 concentration in human samples for both clinical and experimental investigations.
