Used in immunological research to quantify eosinophil levels in rat samples, this ELISA kit enables accurate measurement of eosinophil-associated responses in studies related to allergic inflammation, asthma, parasitic infections, and autoimmune diseases. It supports the evaluation of drug efficacy and toxicity in preclinical models by detecting specific biomarkers linked to eosinophil activation. The kit is suitable for use with serum, plasma, and cell culture supernatants, providing a reliable tool for researchers investigating respiratory and immune system disorders in rodent models.
