Used in biomedical research to quantify Prostaglandin E2 levels in biological samples such as serum, plasma, and cell culture supernatants. Widely applied in studies related to inflammation, immune response, reproductive physiology, and cancer. Enables researchers to assess PGE2 as a biomarker in disease models and evaluate the impact of drugs or treatments on prostaglandin pathways. Suitable for high-throughput screening and detailed mechanistic studies in veterinary and comparative medicine.
