Description: The HM40-3 monoclonal antibody reacts with mouse and rat CD40, a 45-50 kDa type I transmembrane glycoprotein. CD40 is a member of the TNFR family and is expressed by mouse B lymphocytes, follicular dendritic cells, thymic epithelium, and a subset of peripheral T cells. CD40 regulates B cell development/maturation by inducing 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 CD154 (gp39), its ligand on T cells, is important in T-B cell crosstalk and plays a role in costimulation and immune regulation.
Applications Reported: The HM40-3 antibody has been reported for use in flow cytometric analysis.
Applications Tested: The HM40-3 antibody has been tested by flow cytometric analysis of mouse splenocytes and can be used at less than or equal to 1 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

The CD40 antigen is a single chain glycoprotein. It is known to be a member of the tumor necrosis factor / nerve growth factor superfamily and shows a significant homology to the Hodgkin's disease associated antigen, CD30. CD40 is present on all B cells except plasma cells. It is also found on some epithelial cells, carcinomas and lymphoid dendritic cells. The precise function of the CD40 antigen is unknown but it appears to be involved in the transduction of regulatory signals for cellular functions such as B cell proliferation and differentiation.
