CD68 (Cluster of Differentiation 68) is a transmembrane glycoprotein which is highly glycosylated in its extracellular domain and has a molecular weight of 110 kDa. It is found in the cytoplasmic granules of a number of different blood cells and myocytes and is considered to be a marker for cells of the macrophage lineage, including monocytes, histiocytes, giant cells, Kupffer cells, osteoclasts and their precursors.
The antibody recognizes myelomonocytic and histiocytic tumors and may help distinguish malignant fibrous histiocytomas from other pleomorphic sarcomas.
