Specificity: Clone ICRF44 recognizes the alpha subunit (CD11b) of the human CD11b/CD18 complex.
Endotoxin Level: ≤ 1.0 EU/mg as determined by the LAL method. Purity: >95% by SDS Page; ≥95% monomer by analytical SEC.
Product Preparation: Functional grade preclinical antibodies are manufactured in an animal free facility using only In vitro protein free cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.
Storage and Handling: Functional grade preclinical antibodies may be stored sterile as received at 2-8 C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at -80 C. Avoid Repeated Freeze Thaw Cycles.
This antibody has been tested in the following applications: Immunohistochemistry-Fresh Frozen, Immunofluorescence Staining, Flow Cytometry, CODEX®.
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, a subset of dendritic cells, and microglia in the brain. CD11b/CD18 functions as the receptor for ICAM-1 (CD54), ICAM-2 (CD102), ICAM-4 (CD242), CD14, CD50, CD23, heparin, iC3b, fibrinogen, and Factor X -these adhesions are critical for cell-cell and cell-matrix interactions. CD11b is expressed on 8% of spleen cells, 44% of bone marrow cells, and less than 1% of thymocytes, and is commonly used as a microglial marker in nervous tissue. The expression of CD11b increases during monocyte maturation and expression levels vary on tissue macrophages. Further, peritoneal macrophages are reported to express higher levels of CD11b than splenic macrophages. Diseases associated with CD11b dysfunction include systemic lupus erythematosus 6 and ITGAM-related susceptibility to systemic lupus erythematosus.
