Application Notes:

Additional reported applications (for the relevant formats) include: blocking of CD40 ligand binding1, stimulation of mouse B cell and dendritic cell proliferation2-6,9, and immunohistochemistry7 of acetone-fixed frozen sections.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤2.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

* Alexa Fluor® 488 has a maximum emission of 519 nm when it is excited at 488 nm.

C57BL/6 mouse splenocytes stained with HM40-3 Alexa Fluor® 488


CD40 is a 48 kD 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. The HM40-3 antibody has been reported to stimulate dendritic and B cell proliferation and block CD40-CD40L interactions.

Other Names: Bp50
Structure: TNFR superfamily, 48 kD
Distribution: B cells, basal epithelial cells, macrophages, follicular dendritic cells, endothelial cells, CD34+ hematopoietic progenitors
Function: Stimulates B cell growth, differentiation and isotype switching, stimulates macrophage and dendritic cell cytokine production
Ligand Receptor: CD40L (CD154)
