|Other Names||Macrosialin, Gp110, CD68, CD68|
|Target/Specificity||Subcellular fraction of human alveolar macrophages|
|Application Note||Flow Cytometry : 0.5-1ug/million cells|
Immunofluorescence : 0.5-1.0 µg/ml
Western Blotting : 0.5-1.0 µg/ml
Immunoprecipitation : 0.5-1 µg/500ug protein lysate
Immunohistology (Frozen & Formalin-fixed) : 0.5-1.0 µg/ml for 30 minutes at RT
(Staining of formalin-fixed tissues is enhanced by boiling tissue sections in 10mM Citrate Buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes).
|Format||0.5 ml at 200ug/ml with BSA and azide|
|Storage||Store at 2 to 8°C.Antibody is stable for 24 months.|
|Precautions||CD68 (Macrophage Marker) Antibody - With BSA and Azide is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Could play a role in phagocytic activities of tissue macrophages, both in intracellular lysosomal metabolism and extracellular cell-cell and cell-pathogen interactions. Binds to tissue- and organ-specific lectins or selectins, allowing homing of macrophage subsets to particular sites. Rapid recirculation of CD68 from endosomes and lysosomes to the plasma membrane may allow macrophages to crawl over selectin-bearing substrates or other cells.|
|Cellular Location||Isoform Short: Cell membrane; Single-pass type I membrane protein|
|Tissue Location||Highly expressed by blood monocytes and tissue macrophages. Also expressed in lymphocytes, fibroblasts and endothelial cells. Expressed in many tumor cell lines which could allow them to attach to selectins on vascular endothelium, facilitating their dissemination to secondary sites|

This antibody recognizes a glycoprotein of 110kDa, which is identified as CD68. It is important for identifying macrophages in tissue sections. It stains macrophages in a wide variety of human tissues, including Kupffer cells and macrophages in the red pulp of the spleen, in lamina propria of the gut, in lung alveoli, and in bone marrow. It reacts with myeloid precursors and peripheral blood granulocytes. It also reacts with plasmacytoid T cells, which are supposed to be of monocyte/macrophage origin. It shows strong granular cytoplasmic staining of chronic and acute myeloid leukemia and also reacts with rare cases of true histiocytic neoplasia. Lymphomas are negative or show few granules.
