Our Abpromise guarantee covers the use of ab83739 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use a concentration of 5 µg/ml.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 93 kDa (predicted molecular weight: 93 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.


  • Function
    Binds to heparin. Induces cell attachment and spreading and plays a role in cell adhesion. May play a role in extracellular matrix mineralization.
  • Tissue specificity
    Widely expressed with highest levels in aorta, stomach, lower gastrointestinal tract, placenta, uterus and breast. Up-regulated in epithelial ovarian tumors. Not expressed in normal ovaries. Also highly expressed at the tumor periphery of lung carcinoma tissue but not within the tumor. Overexpressed in breast cancers.
  • Sequence similarities
    Contains 1 EMI domain.
    Contains 4 FAS1 domains.
  • Post-translational
    Gamma-carboxyglutamate residues are formed by vitamin K dependent carboxylation. These residues are essential for the binding of calcium.
  • Cellular localization
    Secreted > extracellular space > extracellular matrix.

  • ab83690 at 5 µg/ml staining Periostin in Human heart tissue by Immunohistochemistry (Formalin/PFA-fixed, paraffin-embedded sections).
  • ab83690 at 5 µg/ml staining periostin in Human uterus tissue by Immunohistochemistry (Formalin/PFA-fixed, paraffin-embedded sections).
  • IHC image of ab83739 staining in Hu Aorta formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab83739, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
