  • FunctionBinds tightly to hydroxyapatite. Appears to form an integral part of the mineralized matrix. Probably important to cell-matrix interaction. Promotes Arg-Gly-Asp-dependent cell attachment.
  • Post-translational
    N-glycosylated; glycans consist of sialated and core-fucosylated bi-, tri- and tetraantennary chains.
    O-glycosylated at eight sites; mucin-type glycans contain Gal, GlcNAc, GalNAc and terminal NeuAc.
    Sulfated on either Tyr-313 or Tyr-314.

  • ab52128 (2ug/ml) staining Bone Sialoprotein in human bone using an automated system (DAKO Autostainer Plus). Using this protocol there is strong staining of Bone sialoprotein in sectretory compartments in the cells of the perichondrium
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffers citrate pH6.1 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.
