Flow cytometry analysis of CD11b was performed on untreated (blue line) or ATRA treated (red line) HL-60 cells. After 72 hours incubation with or without 10 µM ATRA, cells were fixed and washed with PBS. Fixed HL-60 cells were incubated with 1 µg of CD11b monoclonal antibody (Product # MA1-19004), followed by incubation with a DyLight 488-conjugated goat-anti-mouse IgG secondary antibody (Product # 35502). To control for non-specific binding, cells were also incubated with secondary antibody only (black line). Incubations were performed for 30 mins in the dark. 10,000 cells at were analyzed for each sample.

CD11b (integrin alphaM subunit) is a 165-170 kDa type I transmembrane glycoprotein that non-covalently associates with integrin beta2 subunit (CD18); expression of the CD11b chain on the cell surface requires the presence of the CD18 antigen. CD11b/CD18 integrin (Mac-1, CR3) is highly expressed on NK cells, neutrophils, monocytes and less on macrophages.
CD11b/CD18 integrin is implicated in various adhesive interactions of monocytes, macrophages and granulocytes, facilitating their diapedesis, as well as it mediates the uptake of complement coated particles, serving as a receptor for the iC3b fragment of the third complement component.
