Used in biomedical research to quantify osteoclast differentiation factor in biological samples, aiding in the study of bone metabolism, osteoporosis, rheumatoid arthritis, and other bone-related diseases. Enables researchers to assess the activity of signaling molecules involved in osteoclast formation and bone resorption. Commonly applied in preclinical drug development to evaluate the efficacy of therapeutic agents targeting bone loss. Suitable for use with serum, plasma, and cell culture supernatants, supporting high-throughput screening and mechanistic studies in cell biology and immunology.
