Used in research and development for targeting interleukin-13 (IL-13), a cytokine involved in inflammatory responses. This antibody serves as a reference standard in assays evaluating IL-13 activity, particularly in studies related to asthma, atopic dermatitis, and other allergic or inflammatory diseases. It is employed in neutralization experiments to confirm target specificity and to benchmark the performance of therapeutic antibodies. Commonly used in ELISA, flow cytometry, and in vitro functional assays to support drug discovery and validation of anti-IL-13 therapeutics.
