Used for the quantitative measurement of Eosinophil Peroxidase (EPX) activity in biological samples from non-human primates. Commonly applied in preclinical research to assess eosinophil-related inflammation, particularly in studies of allergies, asthma, or chronic inflammatory conditions. Helps evaluate immune responses involving eosinophils in monkey models, supporting pharmaceutical development for anti-inflammatory therapies and safety assessment. The ELISA format allows high-throughput analysis with high specificity and sensitivity.
