      ApplicationAnti-CD34 Antibody, Class II, clone QBEND/10 is an antibody against CD34 Class II for use in FC, IP, IH, IH(P).
      Key Applications
      • Flow Cytometry
      • Immunoprecipitation
      • Immunohistochemistry
      • Immunohistochemistry (Paraffin)
      Application NotesIdentification of haemopoietic progenitor cells

      Studies into the control mechanisms of early haemopoiesis

      Purification of haemopoietic cells from, for example, FACS

      The antibody reacts with both frozen and fixed tissue sections from vascular endothelium and stromal fibroblasts

      Immunohistochemistry in parraffin sections: Pretreatment is HIER with citrate buffer, pH 6.0.

      Optimal working dilutions must be determined by the end user.
      Biological Information
      ImmunogenHuman endothelial vesicles
      SpecificityThe antibody recognizes a heavily glycosylated transmembrane protein: gp 105-120 kDa. The antigen is expressed on immature human haemopoietic precursor cells, capillary endothelial cells and human myeloid cells in the following categories: subsets of CFU-GEMM and BFU-E, all CFU-GM, granulocyte precursors, monocytes, myeloid leukaemias. This antibody recognizes the class II epitope showing resistance to neuraminidase enzyme cleavage.

      KNOWN SPECIES CROSS REACTIVITY: Positive with rhesus monkey peripheral blood leucocytes in flow cytometry.

      FUSION PARTNER: NSO myeloma cell line

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P28906 # 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.
      SIZE: 385 amino acids; 40716 Da
      SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
      TISSUE SPECIFICITY: Selectively expressed on hematopoietic progenitor cells and the small vessel endothelium of a variety of tissues.
      DEVELOPMENTAL STAGE: On early hematopoietic progenitor cells.
      PTM: Highly glycosylated. & Phosphorylated on serine residues by PKC.
      DISEASE:SwissProt: P28906 # Abnormal CD34 expression in leukemogenesis.
      SIMILARITY: SwissProt: P28906 ## Belongs to the CD34 family.
