  • General notes

    Though 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.


  • Function

    Cooperates 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 specificity

    Expressed strongly on the surface of monocytes and weakly on the surface of granulocytes; also expressed by most tissue macrophages.
  • Sequence similarities

    Contains 11 LRR (leucine-rich) repeats.
  • Post-translational

    N- and O- glycosylated. O-glycosylated with a core 1 or possibly core 8 glycan.
  • Cellular localization

    Cell membrane.

According to our records, ab39256, ab63319, ab77258, ab86673, ab103674 was proving difficult to use in [APPL] and we were in contact in order to help resolve the issue.

Looking at our correspondence, it appears that we are awaiting more details in order to help us better understand the difficulties experienced. If the requested information has already been sent, it appears that it did not reach our Scientific Support team and we apologize for this inconvenience. In this case we would like to ask for the information again so that we can reach a resolution.

If the issue has already been settled, please let us know so that we can be assured that the problem has been solved to your satisfaction and update our records.

We wish you the best of luck with your research and look forward to a reply.

Thank you for your email.

We will look forward to receive the images. On the optimization note we strongly recommend to include the blocking step in protocol; please try 5%BSA or 5-10% normal serum for 1-2 hours at room temperature with species same as secondary antibody. I am sure this step would improve the staining with ab103674 and ab39256.

I may be that the tissue sections you are using does not express the targets GCET1, ERG, CD14 or express at very low level so could you provide the details tissue type and species of tissue section tested. We are interested in knowing e.g. human brain tissue sections or house heart tissue sections etc.

I would suggest trying range of incubation with microwave e.g. for 5, 10, 15 and 20 minutes. This range would help to get the optimized incubation at which the antigen is maximum exposed.

I hope these suggestions would be helpful. Should you have any further question please do not hesitate to contact us.

Thank you for your email. I am sorry to hear that you have been experiencing problems with this antibody.

I have read the details you have kindly provided and have following further questions for better understanding of the problem;

- I am very surprised that 5 antibodies failed in row? Could you please specify which other antibody worked?
- What is the type and species of tissue used with each antibody? Could you supply staining images?
- Are the tissues paraffin fixed as mentioned in the details or paraformaldehyde fixed and paraffin embedded sections?
- What was the pH of Tris and Citrate buffer?
- Did tyou permeabilize the tissue sections by incubating them with Triton X-100.
- Metanol/ H2O2 blocking used to block the endogenous peroxidases, which gives false staining when HRP conjugated secondary is used. Have you done the blocking with Normal serum or BSA.
- What dilution of primaries were used in each experiment?
- What is the catalogue number of DAKO envision secondary antibody use? Did you use same kit for all the antibodies? What were the other secondary antibodies used?
- Have you used this detection system successfully before?
- Did you tired optimizing the antigen retrieval method?

Please note more information you will provide-resolution will be achieved quickly.

Thank you very much for your cooperation. I will look forward to hearing from you soon.
