Invitrogen™ CD68 Monoclonal Antibody (FA-11), Brilliant Ultra Violet™ 805, eBioscience™

Description

Description This FA-11 monoclonal antibody reacts with mouse CD68, known also as macrosialin. CD68 is a heavily O- and N- glycosylated type I integral membrane protein belonging to the sialomucin family and is closely related to the Lysosomal/endosomal-Associated Membrane Glycoproteins (LAMP). Although commonly used as a pan-macrophage marker, low levels of expression have also been observed in Langerhans cells and conventional dendritic cells. CD68 is mostly localized in the late endosomes and lysosomes with a smaller fraction circulating to the cell surface. In the steady state, only about 10-15% of CD68 is present at the surface. Cell stimulation increases expression of CD68, its transport to cell surface, and results in glycoform remodeling. CD68 binds oxidized LDL and is involved in the process of phagocytosis. Applications Tested This FA-11 antibody has been tested by intracellular staining followed by flow cytometric analysis of mouse bone marrow cells using the Intracellular Fixation & Permeabilization Buffer Set (Product # 88-8824-00) and protocol. Please refer to 'Staining Intracellular Antigens for Flow Cytometry, Protocol A: Two step protocol for intracellular (cytoplasmic) proteins' located at Flow Protocols>. This may be used at less than or equal to 1.0 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 determ...

CD68 (Macrosialin) is a 110 kDa integral membrane glycoprotein predominantly expressed on the intracellular lysomsomes of monocytes and macrophages and to a lesser extent by dendritic cells and peripheral blood granulocytes. Also, CD68 could play a role in phagocytic activities of tissue macrophages, both in intracellular lysosomal metabolism and extracellular cell-cell and cell-pathogen interactions. CD68 is expressed by interdigitating reticulum cells in tonsil and some histiocytic lymphoma or histiocytosis, acute myeloid leukemia (AML), and granulocytic sarcoma. Elevated expression of CD68 has been demonstrated on CD34+ cells in various human malignancies, including several Acute Myeloid Leukemia studies.
