Description: The M18/2 monoclonal antibody reacts with mouse CD18, the 90-95 kDa integrin beta 2 glycoprotein. CD18 is the common beta subunit that non-covalently associates with CD11a (alpha L), CD11b (alpha M) and CD11c (alpha X) to form LFA-1, Mac-1 and gp150/95. Heterodimers of CD18 and the a subunits are expressed broadly by all leukocytes with NK and T cells showing higher density of surface expression. Through the interactions of LFA-1, Mac-1 and gp150/95 with their counter-receptors, CD18 is involved in cellular adhesion and the immune response.
Applications Reported: The M18/2 antibody has been reported for use in flow cytometric analysis.
Applications Tested: The M18/2 antibody has been tested by flow cytometric analysis of mouse splenocytes and bone marrow cells. This can be used at less than or equal to 1.0 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser.
Filtration: 0.2 µm post-manufacturing filtered.
CD18, also known as the integrin beta 2 subunit, is a 90-95 kDa type I transmembrane protein expressed on all leukocytes. It heterodimerizes with the alpha chains of CD11a, CD11b, CD11c, and CD11d to form various leukocyte (beta2) integrins, which are crucial for cellular adhesion and signaling. The CD18/CD11a complex, known as lymphocyte function-associated antigen-1 (LFA-1), plays a significant role in cellular adhesion and inflammatory reactions. CD18 also forms heterodimers with CD11b (Mac-1, CR3), CD11c, and CD11d, contributing to the processes of cell adhesion and cell-surface mediated signaling. These integrins are essential for proper leukocyte migration and mediating intercellular contacts. The absence of CD18 leads to leukocyte adhesion deficiency type I (LAD1), a condition characterized by impaired leukocyte migration. Severe reduction in CD18 expression can result in the development of a psoriasiform skin disease. CD18 is also a target of Mannheimia (Pasteurella) haemolytica leukotoxin, which can mediate leukotoxin-induced cytolysis. Defects in the CD18 gene are the cause of LAD1, and two transcript variants encoding the CD18 protein have been identified. The integrin-mediated responses are often a composite of the functions of its individual subunits, highlighting the importance of CD18 in immune function and disease.
