The CD68 antibody is a widely used tool in immunological and pathological research, primarily targeting the CD68 glycoprotein—a member of the lysosome-associated membrane protein (LAMP) family. CD68 is a transmembrane protein predominantly expressed on the surface and within lysosomes of myeloid cells, including macrophages, monocytes, and certain dendritic cell subsets. Its high glycosylation level contributes to its role in intracellular vesicle trafficking and phagocytosis.
As a histiocytic marker, CD68 antibodies (e.g., clones KP1. PG-M1) are essential for identifying tissue-resident macrophages and inflammatory cells in human and animal tissues via immunohistochemistry (IHC) or immunofluorescence. These antibodies help characterize diseases involving macrophage infiltration, such as atherosclerosis, autoimmune disorders, and tumor-associated macrophage (TAM) studies in cancer.
However, CD68 is not entirely macrophage-specific; low levels may occur in fibroblasts, neutrophils, or some tumor cells. Researchers often pair CD68 with other markers (e.g., CD163. CD206) to improve specificity in macrophage phenotyping. The antibody’s performance varies by tissue fixation methods, with some clones working better in frozen vs. formalin-fixed paraffin-embedded samples.
First described in the 1990s, CD68 antibodies remain foundational in studying innate immunity and tissue inflammation, though newer markers now complement their role in macrophage biology.
