Used in immunological research to quantify eosinophil peroxidase levels in biological samples, this ELISA kit helps assess eosinophil activation and involvement in allergic responses, asthma, and parasitic infections. It enables researchers to measure EPX concentration in cell cultures, serum, or tissue homogenates with high sensitivity and specificity. Commonly applied in studies related to airway inflammation, immune system modulation, and drug development for eosinophilic disorders. The assay supports rapid screening and validation of therapeutic targets in preclinical research.
