WB Use a concentration of 0.5 - 1.5 µg/ml. Detects a band of approximately 30 kDa (predicted molecular weight: 34 kDa).

Blocking peptide available ab45753.


  • FunctionBinds tightly to hydroxyapatite. Appears to form an integral part of the mineralized matrix. Probably important to cell-matrix interaction.
    Acts as a cytokine involved in enhancing production of interferon-gamma and interleukin-12 and reducing production of interleukin-10 and is essential in the pathway that leads to type I immunity.
  • Tissue specificityBone. Found in plasma.
  • Sequence similaritiesBelongs to the osteopontin family.
  • Post-translational
    Extensively phosphorylated on clustered serine residues.
    N- and O-glycosylated.
    Phosphorylation sites are present in the extracelllular medium.
