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 (3).

Isotype: Murine IgG1

Immunogen: Murine L cells transfectants expressing human CD40

Specificity: Antibody BE-1 recognizes the CD40 molecule of about 44 kd (1, 2).

Functional Application: Binding of cross linked BE-1 will partially activate B cells.
