Description: The M1/69 monoclonal antibody reacts with the mouse CD24 molecule, also known as Heat Stable Antigen (HSA). This 35-50 kDa molecule is anchored in the plasma membrane via phosphatidylinositol and is expressed by erythrocytes, thymocytes, peripheral lymphocytes and myeloid lineage. CD24 is a variably glycosylated molecule resulting in heterogeneity of molecular mass of this antigen on cells of different lineages and antibodies to CD24 exhibit subtle differences in staining level on lymphocyte populations. The expression of CD24 has been used to resolve stages of B lymphopoiesis in mouse bone marrow. It has been reported that P-selectin (CD62P) binds to CD24. Applications Reported: This M1/69 antibody has been reported for use in flow cytometric analysis. Applications Tested: This M1/69 antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 0.25 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. eFluor® 450 is an alternative to Pacific Blue®. eFluor® 450 emits at 445 nm and is excited with the Violet laser (405 nm).Please make sure that your instrument is capable of detecting this fluorochome. Excitation: 405 nm; Emission: 445 nm; Laser: Violet Laser. Filtration: 0.2 µm post-manufacturing filtered. CD24 is a two-chain glycosylphosphatidylinositol (GPI)-anchored glycoprotein expressed at multiple stages of B-cell development, beginning with the bone marrow pro-B-cell compartment and continuing through mature, surface Ig positive B-cells. Plasma cell expression is very low or negative. CD24 is also expressed on the majority of B-lineage acute lymphoblastic leukemias, B-cell CCLs and B-cell non-Hodgkin ft.s lymphomas. CD24 may play a role in regulation of B-cell proliferation and maturation, and control of autoimmunity.
