Used in biomedical research to detect and quantify myeloperoxidase (MPO) levels in rat biological samples such as serum, plasma, and tissue homogenates. This kit is essential for studying inflammatory processes, as MPO is a key enzyme released by activated neutrophils and monocytes during inflammation. It is widely applied in research related to cardiovascular diseases, neurodegenerative disorders, and autoimmune conditions in rat models. The assay helps evaluate the extent of oxidative stress and immune activation, providing insights into disease mechanisms and therapeutic interventions.
