ab134674 - Rat monoclonal IgG2a, is suitable for use as an isotype control with this antibody.


  • 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.

Thank you for your enquiry. The protein concentration of this preparation is not measured following conjugation to R-PE as the PE interferes with the estimation of ab concentration, hence the preparation is measured in "tests" as assessed by QC. Howeve...
