CD18 Chimeric Antibody (MA5-48187) in ICC/IF
Immunocytochemistry/Immunofluorescence analysis of CD18 in human peripheral blood monocytes (PBMs) using CD18 Chimeric Monoclonal Antibody (Product # MA5-48187). Paraformaldehyde-fixed cells were immobilized on cover slips and stained with CD18 Chimeric Monoclonal Antibody at 10 µg/mL followed by Alexa Fluor 488 secondary antibody (2 µg/mL), showing membrane staining in a subset of cells. The nuclear stain ... View More

Product Specific Information
Specificity: Specific to the beta chain of the leukocyte integrin beta-2 family. This is found in LFA-1, Mac-1 and p150.95 among others. Binds an epitope distinct from the C3bi binding site. Has been shown to recognise both the human and Rhesus monkey antigen.
Preparation: Blood was obtained from 4 helathy donors and the mononuclear cells harvested and grown. A BALB/c mouse was injected with 10^6 monocytes three times at monthly intervals, and four times with 5x10^6 monocytes oon each of the four days before fusion. The spleen cells were then fused to P3U1 myeloma cells to generate hybridomas and RIA was used to identify lines of interest.
Target Information
CD18 integrin beta 2 subunit is a 90 kDa type I transmembrane protein expressed on all leucocytes. CD18 can combine with integrin molecules CD11a-c to form heterodimers at the cell surface, and these heterodimers are known to participate in the process of cell adhesion as well as cell-surface mediated signaling. CD18 forms heterodimers with four types of CD11 molecule to constitute 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 its individual subunits, and 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. Defects in the CD18 gene are the cause of leukocyte adhesion deficiency type I (LAD1). Two transcript variants encoding the CD18 protein have been identified.
