Used in biomedical research to measure levels of procollagen type I C-terminal propeptide in serum or plasma samples. Helps assess bone formation and turnover, making it valuable in studies of osteoporosis, metabolic bone diseases, and connective tissue disorders. Commonly applied in clinical labs and pharmaceutical research to monitor response to bone-anabolic therapies or anti-resorptive treatments. Provides a sensitive and specific quantification method for evaluating collagen synthesis in vivo.
