Used in biomedical research to measure uncarboxylated osteocalcin levels in rat serum or plasma samples. This assay helps in studying bone metabolism, osteoblast activity, and the endocrine functions of bone. Researchers apply this kit in investigations related to glucose metabolism, insulin sensitivity, and energy homeostasis, as uncarboxylated osteocalcin is linked to these physiological processes. It is also utilized in studies assessing the impact of drugs, hormones, or dietary interventions on bone health and metabolic regulation in rodent models.
