Used to measure Prostaglandin E2 levels in biological samples such as serum, plasma, urine, and cell culture supernatants. Widely applied in research settings to study inflammation, immune responses, and pain mechanisms. Helps investigate conditions like arthritis, asthma, and cancer where PGE2 plays a key regulatory role. Also used in pharmacological studies to evaluate drug effects on prostaglandin pathways. Provides a sensitive and specific quantitative analysis, supporting both clinical research and basic science investigations.
