  • Function
    Constitutes 1-2% of the total bone protein. It binds strongly to apatite and calcium.
  • Sequence similarities
    Belongs to the osteocalcin/matrix Gla protein family.
    Contains 1 Gla (gamma-carboxy-glutamate) domain.
  • Post-translational
    Gamma-carboxyglutamate residues are formed by vitamin K dependent carboxylation. These residues are essential for the binding of calcium.

  • ab13418 staining Osteocalcin in Human bone marrow stem cells tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was blocked with 5%BSA + TBS  + 0,5%Tween for 10 minutes. Samples were incubated with primary antibody (1/80) for 14 hours. An undiluted Biotin-conjugated Donkey polyclonal was used as the secondary antibody.
