Anti-CD40 (Tumor Necrosis Factor Receptor Superfamily Member 5, B Cell Surface Antigen CD40, Bp50, C

CD40 is a 48kD type I transmembrane glycoprotein, also known as Bp50. It is a member of the tumor necrosis factor receptor (TNFR) superfamily, expressed on B cells, basal epithelial cells, macrophages, follicular dendritic cells, endothelial cells, and a subset of CD34+ hematopoietic progenitors. CD40 regulates B cell development/maturation, Ig isotype switching and, in combination with other signals such as IL-4, protects B cells from surface Ig-induced apoptosis and promotes proliferation. Interaction of CD40 with its ligand CD154 (gp39) expressed on activated T cells, is important in costimulation and immune regulation. This antibody has been reported to stimulate dendritic and B cell proliferation and block CD40-CD40L interactions. Applications: Suitable for use in Flow Cytometry and Immunohistochemistry.
