Used in bone metabolism research to quantify type I collagen degradation, this kit helps assess bone resorption levels. It is commonly applied in studies related to osteoporosis, metabolic bone diseases, and the evaluation of anti-resorptive drug efficacy. The assay enables researchers to measure NTX-I levels in urine or serum samples, providing a non-invasive and sensitive marker for monitoring bone turnover in preclinical and clinical investigations. It supports research in aging, menopause, cancer metastasis to bone, and orthopedic conditions.
