The 5C3 monoclonal antibody specifically reacts with human CD40, a 48kDA type I glycoprotein. CD40 is part of the TNFR family and expressed on a subset of T cells, B cells, dendritic cells, and macrophages. It has been shown to be involved in the protection of B cells from apoptosis, B cell differentiation, co-stimulation, and isotype class-switching. The 5C3 antibody partially blocks the binding of CD40L (CD154). In the presence of IL-4 or PMA, the 5C3 antibody promotes B cell proliferation.
