2. Description: The peptide hormone osteocalcin consists of 49 amino acids and is synthesized in the bone by osteoblasts. Osteocalcin is used as a marker for bone formation and bone regeneration, as it regulates bone mineralization. The vitamin K-dependent osteocalcin synthesis is stimulated by vitamin D. Only through successful post-translational carboxylation by vitamin K is osteocalcin able to bind calcium and supply it to the bone matrix. A deficiency of vitamin K and D thus leads to a lower carboxylation, which is associated with a lower bone density and a higher risk of bone fracture. Due to its pleiotropic mechanism of action, Osteocalcin influences not only the mineralization of bones but also insulin secretion, the breakdown of fat cells and the stimulation of androgens.
3. Stability: Stable at -20°C for 6 months.
