Human CD40 is a member of the tumor necrosis factor (TNF) receptor family and is present on all B cells except plasma cells. CD40 is also found on some epithelial cells, carcinomas and lymphoid dendritic cells. CD40 plays an important role in B cell activation and the interaction with its ligand CD154 (CD40 Ligand) is essential for isotype switching (5).
Isotype: Murine IgG1
Immunogen: Murine L cells transfectants expressing human CD40
Specificity: Antibody EA-5 recognizes the CD40 molecule of about 44 kd (1, 2, 3).
Functional Application: Binding of cross linked EA-5 will partially activate B cells.
