Klon: MEM-148

Beschreibung: CD18, integrin beta2 subunit, forms heterodimers with four types of CD11 molecule toconstitute leukocyte (beta2) integrins: alphaLbeta2 (CD11a/CD18, LFA-1), alphaMbeta2(CD11b/CD18, Mac-1, CR3), alphaXbeta2 (CD11c/CD18) and alphaDbeta2 (CD11d/CD18).In most cases, the response mediated by the integrin is a composite of the functions of itsindividual subunits. These integrins are essential for proper leukocyte migration, mediatingintercellular contacts. Absence of CD18 leads to leukocyte adhesion deficiency-1, severereduction 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 tomediate leukotoxin-mediated cytolysis.

Spezifität: The antibody MEM-148 recognizes an epitope on CD18 which is essentially inaccessible inintact integrin molecules on resting leukocytes, but is exposed on high-affinity state of LFA-1or on unassociated CD18. CD18 (integrin beta2 subunit, beta2 integrin) is a 90-95 kDa typeI transmembrane protein expressed on all leukocytes.HLDA VI, WS Code AS A052 This antibody does not react with: Porcine.
