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).
