Application Notes:

The 1C10 antibody has been reported to stimulate B cell proliferation and block CD40-CD40L interactions. Additional reported applications (for the relevant formats) include: immunoprecipitation, blocking5,6 of CD40 ligand binding, and in vitro stimulation of B cell proliferation1-3.

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 ≤1.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

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 and is 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), which is expressed on activated T cells, is important in costimulation and immune regulation.

Other Names: Bp50, TNFRSF5
