Immunogen Peripheral blood mononuclear cells.
Clone MEM-148
Isotype IgG1
Specificity The antibody recognizes the epitope exposed on free human CD18 chains unassociated with CD11 as well as on high-affinity state of LFA-1. CD18 (integrin b2 subunit, b2 integrin) is a 90-95 kDa type I transmembrane protein expressed on all leukocytes.
Cross-Reactivity (Details) Species reactivity (tested):Human. Negative with Porcine.
Purification Protein A Affinity Chromatography
Alternative Name CD18 / ITGB2 (ITGB2 Antibody Abstract)
Background 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
