Description

The HM40-3 monoclonal antibody reacts with mouse 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. HM40-3 has been reported in the literature to cross-react with the rat CD40 antigen.

Applications Reported

For research use only, not for diagnostic or therapeutic use. 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 splenocyte suspensions and can be used at less than or equal to 1 μg/million cells. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
