Product Specific Information
This antibody detects an extracellular epitope of CD11b (integrin alphaM subunit), a type I transmembrane protein mainly expressed on monocytes/macrophages, granulocytes, and NK cells. It associates with CD18 to form the Mac-1 integrin complex, which plays an important role in cell-cell interactions.
Target Information
CD11b (integrin alpha-M, ITGAM, integrin alpha-X, ITGAX) is a 165 kDa adhesion molecule that associates non-covalently with integrin beta-2 (CD18). The CD11b/CD18 heterodimeric complex is also known as integrin alpha-M beta-2, Mac-1, and CR3 (complement receptor 3).
CD11b is expressed on the surface of:
- Monocytes/macrophages
- Granulocytes
- Activated lymphocytes
- A subset of NK cells and dendritic cells
- Microglia in the brain
Functions and Binding Partners:
- Acts as a receptor for ICAM-1 (CD54), ICAM-2 (CD102), ICAM-4 (CD242), CD14, CD50, CD23, heparin, iC3b, fibrinogen, and Factor X.
- Plays key roles in cell-cell and cell-matrix adhesion.
Expression Patterns:
- 8% of spleen cells
- 44% of bone marrow cells
- <1% of thymocytes
- Commonly used as a microglial marker in nervous tissue.
- Expression increases during monocyte maturation.
- Peritoneal macrophages express higher CD11b levels than splenic macrophages.
Associated Diseases:
- Systemic lupus erythematosus (SLE)
- ITGAM-related susceptibility to SLE
