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

Application Abreviews Notes
Flow Cyt Use a concentration of 1 µg/ml. ab170190-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
IHC-P Use a concentration of 10 µg/ml.
IP Use at an assay dependent concentration.
WB 1/100. Use under non-reducing conditions.
Functional Studies Use at an assay dependent concentration. The antibody activates T lymphocytes and also induces apoptosis in hemopoietic progenitor cells.


  • Function
    One 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 specificity
    Cell 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.
