Used in veterinary research to measure Prostaglandin E2 levels in canine biological samples such as serum, plasma, or tissue homogenates. Helps in studying inflammation, reproductive health, and immune responses in dogs. Commonly applied in clinical studies to assess disease progression, evaluate treatment efficacy, and understand physiological pathways involving prostaglandins. Suitable for research on conditions like arthritis, pyometra, and kidney disease where PGE2 plays a regulatory role. Provides a sensitive and specific method for quantifying PGE2 without the need for radioisotopes or HPLC.
