Used in bone metabolism studies to measure bone resorption, this ELISA research kit detects the C-terminal telopeptide of type I collagen (CTX-I), a biomarker released during bone breakdown. It is widely applied in osteoporosis research and drug development to assess the effectiveness of anti-resorptive therapies. The kit enables quantitative analysis of CTX-I in serum or plasma samples, providing researchers with a reliable tool to monitor changes in bone turnover in preclinical and clinical settings. It is especially useful in studies involving menopause, aging, and metabolic bone diseases.
