Used to measure myeloperoxidase (MPO) activity in biological samples such as serum, plasma, or tissue homogenates from mice. This assay helps assess inflammation levels, particularly in research related to cardiovascular diseases, neurodegenerative disorders, and autoimmune conditions. It is commonly used in preclinical studies to evaluate the effectiveness of anti-inflammatory treatments by monitoring changes in MPO levels, which reflect neutrophil activation and oxidative stress. The kit provides a sensitive and specific way to quantify MPO, enabling researchers to draw correlations between enzyme activity and disease progression or intervention outcomes.
