Extra Details:: 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. Applications: Suitable for use in Flow Cytometry, ELISA, Western Blot, and Immunocytochemistry. Other applications not tested. Recommended Dilution: Flow Cytometry: 1:50 Western Blot: 1:100-1000 Immunocytochemistry: 1:50-500 Optimal dilutions to be determined by the researcher.
