CD11b/c Products

CD11b, also known as Integrin alpha M, is one half of the heterodimeric integrin alpha-M beta-2 molecule. This protein mediates inflammation by regulating leukocyte adhesion and migration and has been implicated in several immune processes such as phagocytosis, cell-mediated cytotoxicity, chemotaxis and cellular activation. CD11b is expressed on the surface of many leukocytes involved in the innate immune system, including monocytes, granulocytes, macrophages, and natural killer cells. Mutations in the CD11b protein have been assosicated with the autoimmune disease lupus, and CD11b antibodies are therefore commonly in immunology studies.

CD11c, also known as Integrin alpha X, is a type I transmembrane protein found at high levels on most human dendritic cells, but also on monocytes, macrophages, neutrophils, and some B cells that induces cellular activation and helps trigger neutrophil respiratory burst; expressed in hairy cell leukemias, acute nonlymphocytic leukemias, and some B-cell chronic lymphocytic leukemias.
