Used in the research and development of therapeutics for autoimmune neuromuscular disorders, particularly MuSK-associated myasthenia gravis. This antibody serves as a reference tool to study antibody-mediated pathogenic mechanisms, evaluate drug candidates, and support the development of targeted biologics. It is instrumental in competitive binding assays and functional studies to assess neutralization or interference with pathogenic autoantibodies. Due to its well-characterized specificity and function, it supports quality control and consistency in biosimilar or novel therapeutic antibody development.
