Human CD18 (beta integrin) forms a heterodimer with either alpha L, alpha M, or alpha X integrins (CD11a, b or c). CD11/CD18 heterodimeric molecules are involved with cell/cell and cell/extracellular adhesion in immune and inflammatory responses.
Isotype: Murine IgG2a
Immunogen: Human peripheral blood monocytes
Specificity: Antibody IB4 recognizes the beta 2 integrin subunit (CD18) adhesion molecule of about 95 kd (1, 6).
Functional Application: Antibody IB4 blocks binding of ICAM-1 and ICAM-3 to LFA-1 (2, 5).
