Used in research and development for targeting interleukin-13 (IL-13) pathways, this antibody serves as a reference standard in immunoassays and bioassays to evaluate the potency and specificity of anti-IL-13 therapeutics. It supports the calibration of analytical methods in preclinical and clinical studies focused on inflammatory diseases, particularly asthma, atopic dermatitis, and other allergic conditions where IL-13 plays a key role. Its high specificity makes it valuable for quantifying neutralizing activity and binding affinity in quality control and comparative studies of biosimilars or novel biologics.
