Used in biomedical research to measure procollagen type I amino-terminal propeptide (PINP) levels in biological samples, serving as a biomarker for bone formation. Helps assess bone turnover in studies related to osteoporosis, metabolic bone diseases, and fracture risk. Widely applied in preclinical research and clinical trials to monitor the effectiveness of bone-active therapies such as anabolic or antiresorptive agents. Also utilized in endocrinology and rheumatology research to understand bone metabolism changes in response to hormonal imbalances, aging, or inflammatory conditions. Provides a sensitive and specific quantitative measurement, supporting high-throughput analysis in serum or plasma samples.
