Used in research settings to measure osteocalcin levels in human biological samples such as serum or plasma. This kit helps assess bone formation and turnover, making it valuable in studies related to osteoporosis, metabolic bone diseases, and endocrine disorders. It is also applied in clinical research to evaluate the effectiveness of treatments affecting bone metabolism, including hormone therapies and anti-resorptive drugs. The assay provides a sensitive and specific quantitative measurement, supporting investigations in bone health, aging, and energy metabolism where osteocalcin plays a regulatory role.
