The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Flow Cyt Use 1µl for 106 cells. ab91356-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.


  • FunctionOne of the major glycoproteins of thymocytes and T lymphocytes. Plays a role in the physicochemical properties of the T-cell surface and in lectin binding. Presents carbohydrate ligands to selectins. Has an extended rodlike structure that could protrude above the glycocalyx of the cell and allow multiple glycan chains to be accessible for binding. Is a counter receptor for SN/Siglec-1 (By similarity). During T-cell activation is actively removed from the T-cell-APC (antigen-presenting cell) contact site thus suggesting a negative regulatory role in adaptive immune response.
  • Tissue specificityCell surface of thymocytes, T-lymphocytes, neutrophils, plasma cells and myelomas.
  • Post-translational
    Glycosylated; has a high content of sialic acid and O-linked carbohydrate structures.
  • Cellular localizationMembrane.

  • Flow Cytometry analysis of human peripheral blood cells labeling CD43 with Anti-CD43 antibody [MEM-59] (FITC) (ab21853).
  • Overlay histogram showing peripheral blood lymphocytes stained with ab21853(red line). The cells incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab21853, 0.5 µg/1x106 cells) for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 FITC (2 µg/1x106 cells ) for 30 min at 22°C. Acquisition of >5,000 events was performed.
