Human CD11c (alpha X integrin) complexes with CD18 (beta 2 integrin) to form the complement receptor type 4 (CR4) heterodimer which binds to fibrinogen and is involved with monocyte/granulocyte adhesion during inflammatory responses (2). CD11c expression is restricted to leukocytes mainly of myeloid lineage with highest expression on macrophages.
Isotype: Murine IgG1
Immunogen: Human rheumatoid synovial fluid cells/monocytes
Specificity: Antibody 3.9 recognizes the human integrin alpha X subunit (CD11c) of about 150 kd (1, 4). It is cross reactive with cynomolgus monkey CD11c (5).
