Used in research and development for autoimmune disease therapies, particularly in studies related to inflammation and immune regulation. It serves as a reference standard in assays evaluating IL-17a pathway inhibition, supporting the development of biosimilars and novel biologics. Commonly applied in ELISA, flow cytometry, and neutralization assays to measure target binding and functional activity. Supports quality control and cross-comparison between different anti-IL-17a therapeutic candidates in preclinical and clinical stages.
