Flow Cyt
  • Application notes
    Flow Cyt: Use neat. Use 10ul to label 106 cells in 100ul.
    IHC-Fr: Use at an assay dependent dilution.
    IHC-P: Use at an assay dependent dilution. This product requires protein digestion pre-treatment of paraffin sections, eg.trypsin or pronase.

    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • Function
      Immunoglobulin-like cell surface receptor for CD47. Acts as docking protein and induces translocation of PTPN6, PTPN11 and other binding partners from the cytosol to the plasma membrane. Supports adhesion of cerebellar neurons, neurite outgrowth and glial cell attachment. May play a key role in intracellular signaling during synaptogenesis and in synaptic function (By similarity). Involved in the negative regulation of receptor tyrosine kinase-coupled cellular responses induced by cell adhesion, growth factors or insulin. Mediates negative regulation of phagocytosis, mast cell activation and dendritic cell activation. CD47 binding prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells.
    • Tissue specificity
      Ubiquitous. Highly expressed in brain. Detected on myeloid cells, but not T-cells. Detected at lower levels in heart, placenta, lung, testis, ovary, colon, liver, small intestine, prostate, spleen, kidney, skeletal muscle and pancreas.
    • Sequence similarities
      Contains 2 Ig-like C1-type (immunoglobulin-like) domains.
      Contains 1 Ig-like V-type (immunoglobulin-like) domain.
    • Post-translational
      Phosphorylated on tyrosine residues in response to stimulation with EGF, growth hormone, insulin and PDGF. Dephosphorylated by PTPN11.
