Invitrogen™ CD24 Monoclonal Antibody (SN3), PE-Alexa Fluor™ 610

CD24 is a 35-50 kDa glycosylphosphatidylinositol (GPI)-anchored glycoprotein expressed on a variety of cell types, including erythrocytes, thymocytes, peripheral lymphocytes, and cells of the myeloid lineage. It is variably glycosylated, resulting in heterogeneity in molecular mass across different cell lineages, which can affect antibody staining levels on lymphocyte populations. In the context of B-cell development, CD24 is expressed from the pro-B-cell stage in the bone marrow through to mature, surface Ig-positive B cells, with very low or negative expression on plasma cells. It is also present on the majority of B-lineage acute lymphoblastic leukemias, B-cell chronic lymphocytic leukemias (CCLs), and B-cell non-Hodgkin's lymphomas. CD24 is thought to play a role in regulating B-cell proliferation and maturation, as well as in controlling autoimmunity. Additionally, CD24 has been reported to interact with P-selectin (CD62P), indicating a potential role in cell adhesion and signaling. CD24 is a valuable marker for studying B-cell development, leukemia, lymphoma, and autoimmune regulation, as well as its interactions with other molecules like P-selectin.
