Used in biomedical research to measure GDF-11 protein levels in biological samples such as serum, plasma, and cell culture supernatants. Enables scientists to study the role of GDF-11 in aging, tissue regeneration, and metabolic regulation. Commonly applied in studies related to muscle rejuvenation, neurodegenerative diseases, and age-related decline. Provides a reliable, sensitive, and high-throughput method for quantifying GDF-11, supporting both basic research and preclinical development.
