Used in bone metabolism research to quantify levels of procollagen type I N-terminal propeptide, a biomarker for bone formation. Helps assess osteoblastic activity and monitor bone turnover in studies related to osteoporosis, fracture healing, and metabolic bone diseases. Enables researchers to evaluate the effectiveness of therapeutic interventions targeting bone growth or resorption. Commonly applied in preclinical studies and clinical research involving serum or plasma samples.
