Flow Cyt Use 10µl for 106 cells.

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.
  • Cellular localization

Thank you for your inquiry. In this case, a rat IgG-PE isotype control would be ok. However, I suggest that it would be preferable and more appropriate to use a rat IgG2a-PE conjugated isotype control if possible Unfortunately, I am sorry to confirm we do not have any rat IgG2a-PE isotype controls available in our catalogue. I would like to recommend checking the Biocompare website which has an excellent antibody search facility that includes many suppliers. The links are: www.biocompare.com http://www.biocompare.com/ProductCategories/2045/Antibodies.html I hope this information is helpful to you. Please do not hesitate to contact me if you have any further questions.

Thank you for your enquiry. Unfortunately we are not able to accurately measure the concentration of PE-conjugated antibodies but I can give you an approximate concentration for ab23830, which is 0.1mg/ml. I hope this information will be helpful. Should you require any other information, please do not hesitate to contact me.

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. However as a guide, the approximate concentration of this antibody is 0.1mg/ml. The IgG was purified on Protein G prior to conjugation. If you have any further questions then please do not hesitate to get back in touch with me.
