  • Target

    • Function

      Modulates B-cell activation responses. Signaling could be triggered by the binding of a lectin-like ligand to the CD24 carbohydrates, and transduced by the release of second messengers derived from the GPI-anchor. Promotes AG-dependent proliferation of B-cells, and prevents their terminal differentiation into antibody-forming cells.
    • Tissue specificity

      B-cells. Expressed in a number of B-cell lines including P32/SH and Namalwa. Expressed in erythroleukemia cell and small cell lung carcinoma cell lines. Also expressed on the surface of T-cells.
    • Involvement in disease

      Genetic variations in CD24 are associated with susceptibility to multiple sclerosis (MS) [MIM:126200]. A multifactorial, inflammatory, demyelinating disease of the central nervous system. Sclerotic lesions are characterized by perivascular infiltration of monocytes and lymphocytes and appear as indurated areas in pathologic specimens (sclerosis in plaques). The pathological mechanism is regarded as an autoimmune attack of the myelin sheat, mediated by both cellular and humoral immunity. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia and bladder dysfunction. Genetic and environmental factors influence susceptibility to the disease. Note=Polymorphisms in CD24 may act as a genetic modifier for susceptibility and progression of MS in some populations, perhaps by affecting the efficiency of CD24 expression on the cell surface.

    Thank you for your enquiry regardingab77219 and for taking the time to provide some useful details of the experiments. I am very sorry to hear that you are having problems with this antibody.

    CD24 is a cell surface marker and it is a high change to damage th epitope during enzymatic digestion. Has the customer tried EDTA or scraping off the cells from the tissue culture dish instead of applying trypsin for harvesting the cells.

    It may be worth performing a quick ICC/IF staining to see if the antibody detects CD24 or accidentally damaged.

    I hope this will be useful for you. Should you still have any problem with this antibody after following these suggestions, then please do not hesitate to contact our Technical Department again.

    The antibody ab77219 is supplied at 18ug/ml and although the lab did not provide the total volume supplied, we do guarantee that there will be enough volume present to carry out 100 tests and if you happen to be short then we will send a replacement to make up the volume. Based on the notes on the website, it is recommended use 20µl per 100µl of whole blood or 106 cells in suspension for flow cytometry.

    Please let me know if there is anything else I can help you with.

    Thanks for your reply and for the information. Ab77219 and ab81424 have been tested in flow cytometry and are guaranteed to work in FC with human cells. You are correct, they have not been tested in ICC/IF, and it is possible that they will work but we just don't have any information about this. Please let me know if you have any questions about these antibodies or if there is anything else that we can help with.
