Description: CD11b (integrin aM subunit) is a 165 kDa type I transmembrane glycoprotein that non-covalently associates with integrin b2 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. The expression of CD11b increases during monocyte maturation and expression levels vary on tissue 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. Peritoneal macrophages are reported to express higher levels of CD11b than splenic macrophages. Alternate Names: ITGAM, CD11B, CR3A, Integrin alpha-M, CR-3 alpha chain, MAC-1, Cell surface glycoprotein MAC-1 subunit alpha, Leukocyte adhesion receptor MO1, Neutrophil adherence receptor, CD11 antigen-like family member B.

Application Details

Application Notes: Flow Cytometry: Use 10 ul of neat-1/10 diluted antibody to label 10e6 cells in 100ul. The Fc region of monoclonal antibodies may bind non-specifically to cells expressing low affinity Fc receptors. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

Concentration: 100 Tests

Buffer: PBS, pH 7.4 containing 0.09% Sodium Azide as preservative and 1% BSA as stabilizer.

Storage: Prior to and following reconstitution store the antibody undiluted at 2-8°C. DO NOT FREEZE! This product is photosensitive and should be protected from light. Shelf Life: one year from despatch. Reconstitution: Restore with distilled water..
