This antibody recognizes an epitope involving residues 534-546 in cysteine-rich repeat 3 of the CD18 antigen (integrin b2 subunit, b2 integrin). CD18 is a 90-95 kDa type I transmembrane protein expressed on all leukocytes.

CD18, integrin b2 subunit, forms heterodimers with four types of CD11 Molecule to constitute leukocyte (b2) integrins: aLb2 (CD11a/CD18, LFA-1), aMb2 (CD11b/CD18, Mac-1, CR3), aXb2 (CD11c/CD18) and aDb2 (CD11d/CD18). In most cases, the response mediated by the integrin is a composite of the functions of its individual subunits. These integrins are essential for proper leukocyte migration, mediating intercellular contacts. Absence of CD18 leads to leukocyte adhesion deficiency-1, severe reduction of CD18 expression leads to the development of a psoriasiform skin disease. CD18 is also a target of Mannheimia (Pasteurella) haemolytica leukotoxin and is sufficient to mediate leukotoxin-mediated cytolysis.Synonyms: 95 subunit beta, Cell surface adhesion glycoproteins LFA-1/CR3/p150, Complement receptor C3 subunit beta, Integrin beta-2, MFI7
