  • General notesThough we have received a positive Abreview for this antibody in IHC-P, we have also received many negative reports in IHC-P and so we can no longer guarantee this antibody in this application. We appreciate any further feedback from users in this regard.

    ab63319 reacts with peripheral blood monocytes and weakly with granulocytes. It is negative to platelets, erythrocytes and lymphocytes. It is sometimes positive for chronic myeloid leukemia (CML) and acute myeloid leukemia (AML). It is negative to B-cell chronic lymphocytic leukemia (B-CLL), T-cell chronic lymphocytic leukemia (T-CLL) and common acute lymphoblastic leukemia (CALL).



Our Abpromise guarantee covers the use of ab63319 in the following tested applications.

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

Application Abreviews Notes
Flow Cyt 1/25. Dilute with isotonic buffer. Use 50ul per 1x106 peripheral blood mononuclear cells (PBMC) in 100ul buffer.

ab170190-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
ICC/IF 1/25.
IHC-Fr 1/25. We recommend acetone fixation.


  • FunctionCooperates with MD-2 and TLR4 to mediate the innate immune response to bacterial lipopolysaccharide (LPS). Acts via MyD88, TIRAP and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. Up-regulates cell surface molecules, including adhesion molecules.
  • Tissue specificityExpressed strongly on the surface of monocytes and weakly on the surface of granulocytes; also expressed by most tissue macrophages.
  • Sequence similaritiesContains 11 LRR (leucine-rich) repeats.
  • Post-translational
    N- and O- glycosylated. O-glycosylated with a core 1 or possibly core 8 glycan.
  • Cellular localizationCell membrane.

  • ab63319 staining CD14 in human tonsil tissue sections by IHC-Fr (formaldehyde-fixed frozen sections). Tissue samples were fixed with formaldehyde; antigen retrival was by heat mediation in EDTA (pH8) for 20 minutes at 100°C. The sample was incubated with primary antibody (1/300) at 25°C for 20 minutes. An undiluted HRP-conjugated Goat polyclonal to mouse/rabbit IgG was used as secondary antibody.
