  • Function
    Possible adhesion molecule with a role in early hematopoiesis by mediating the attachment of stem cells to the bone marrow extracellular matrix or directly to stromal cells. Could act as a scaffold for the attachment of lineage specific glycans, allowing stem cells to bind to lectins expressed by stromal cells or other marrow components. Presents carbohydrate ligands to selectins.
  • Tissue specificity
    Selectively expressed on hematopoietic progenitor cells and the small vessel endothelium of a variety of tissues.
  • Sequence similarities
    Belongs to the CD34 family.
  • Developmental stage
    On early hematopoietic progenitor cells.
  • Post-translational
    Highly glycosylated.
    Phosphorylated on serine residues by PKC.
  • Cellular localization

  • IHC image of CD34 staining in Human normal placenta 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 ab762, 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.
