  • 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.

  • Staining of human peripheral blood granulocytes with SN3 mouse monoclonal anti-human CD24 FITC conjugated (ab30350)
  • ab30350 staining CD24 in human pancreatic adenocarcinoma cells by ICC/IF (immunocytochemistry/immunofluorescence). Cells were PFA fixed and blocked with 3% BSA for 30 minutes at 24°C. The primary antibody (1/200 in 1%BSA in PBS) was incubated with the sample for 16 hours at 4°C. An Alexa Fluor® 488-conjugated goat anti-mouse IgG polyclonal (1/300) was used as the secondary.

Thank you for contacting us. In general, the immunoglobulin class (IgG1, IgG2a, IgGM, etc.) and light chain sub-class (kappa or lambda) is listed on the online datasheet. When the light chain is not listed, then the light chain sub-class has not been determined. In these instances, it is probably that the light chain sub-class is kappa, given that murine serum immunoglobulins are 95% kappa and 5% lambda, as discussed in the reference at the following link: http://www.ncbi.nlm.nih.gov/pubmed/3116408 Mol Immunol. 1987 Jul;24(7):751-7. PMID:3116408 Of the antibodies your customer has enquired about, The light chain sub-class has been determined for three: ab90960, ab86896, and ab1385. All are kappa light chain. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for your enquiry. We do not have a CD44 antibody that is directly flurophore labelled that has been shown to work by BOTH IHC-Fr and IHC-P. However, we do have the following unconjugated antibody shown to work by both applications: ab23844 CD44 antibody [MAC329] Rat Monoclonal FACS, IHC-Fr, IHC-P, IP. We have the follwing antibodies that are fluorphore conjugated but only shown to work in IHC-Fr: ab19618 CD44 antibody [IM7] Phycoerythrin conjugated Rat Monoclonal FACS, IHC-Fr, IP. ab19622 CD44 antibody [IM7] FITC conjugated Rat Monoclonal FACS, IHC-Fr, IP. With respect to CD24; again we do not have an antibody that has been shown to work by both IHC-P and IHC-Fr. However, we do have directly conjugated antibodies that have been shown to work by IHC-Fr. They are as follows: ab25657 CD24 antibody [91] FITC conjugated Rat Monoclonal FACS, IHC-Fr, IP ab25281 CD24 antibody [91] PE/Cy5 conjugated Rat Monoclonal FACS, IHC-Fr, IP ab25646 CD24 antibody [91] Phycoerythrin conjugated Rat Monoclonal FACS, IHC-Fr, IP I consider your best option using a combination of the rat monoclonal antibodies according to the wavelengths that you can detect with your fluorescence microscope. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.
