Confocal immunofluorescent analysis of THP-1 cells, differentiated with TPA (12-O-Tetradecanoylphorbol-13-Acetate) #4174 (80 nM, 24 hr) followed by 24 hr without TPA, (left, positive) or HeLa cells (right, negative), using CD11c (3.9) Mouse mAb (green). Samples were mounted in ProLong® Gold Antifade Reagent with DAPI #8961 (blue).
|Immunofluorescence (Immunocytochemistry)||1:200 - 1:800|
Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA, 50% glycerol and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalently purified water.
Recommended Fluorochrome-conjugated Anti-Mouse secondary antibodies:
NOTE: Cells should be grown, treated, fixed and stained directly in multi-well plates, chamber slides or on coverslips.
NOTE: All subsequent incubations should be carried out at room temperature unless otherwise noted in a humid light-tight box or covered dish/plate to prevent drying and fluorochrome fading.

CD11c (3.9) Mouse mAb recognizes endogenous levels of total CD11c protein.
This monoclonal antibody was purified from tissue culture supernatant via affinity chromatography.
CD11c (integrin αX, ITGAX) is a transmembrane glycoprotein that forms an α/β heterodimer with CD18 (integrin β2), which interacts with a variety of extracellular matrix molecules and cell surface proteins (1). CD11c is primarily used as a dendritic cell marker. Dendritic cells can be classified into two major types: CD11c+ conventional dendritic cells that specialize in antigen presentation, and CD11c- plasmacytoid dendritic cells that specialize in type I interferon production (2, 3). CD11c expression has also been observed on activated NK cells, subsets of B cells, monocytes, granulocytes, and some B cell malignancies including hairy cell leukemia (4-7).
