Expression Host:
NSO Cells
Formulation:
This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 with no calcium, magnesium, or preservatives.
Background:
CD40 is a 48 kD type I transmembrane glycoprotein that is a member of the TNFR superfamily. CD40, in association with its ligand CD154 (CD40L) – a 39 kD protein, acts as a costimulatory molecule for the activation of B cells, dendritic cells, monocytes, and other antigen presenting cells. CD40 is involved in Ig isotype switching and dendritic cell maturation, as well as the activation, differentiation and proliferation of B cells. CD40 interacts with TNFR2 and is involved in the regulation of signal transduction. CD40 is a potential target for cancer immunotherapy. Blocking the interaction of CD40 with its ligand (CD154) is the sought-after therapeutic objective for preventing and/or improving both autoimmune diseases and transplant rejection. Studies have shown that monoclonal antibodies that block CD154 in human clinical trials resulted in unanticipated vascular complications. Hence, an interest in the therapeutic potential for antagonist mAbs specific for human CD40 is emerging. Antibodies of particular therapeutic interest are those that do not inhibit CD40 signaling via physical competition with CD154. Additionally, the interaction of CD40 and its ligand (CD154) is found to be essential for amyloid-beta-induced microglial activation, thus plays a significant part in Alzheimer disease pathogenesis.
Other Names:
CD154, TNFSF5, TNFRSF5, TNF Receptor 5, Bp50, CD40
Purity:
>90% by SDS-PAGE and analyzed by silver stain.
Biological Activity:
The biological activity of Mouse CD40 was determined by its ability to inhibit rmCD40 ligand-induced B cell proliferation. The expected ED50 for this effect is typically 0.1-0.3 μg/ml in the presence of 100 ng/ml recombinant mouse CD40 ligand.
Endotoxin level:
<1.0 EU/ug as determined by the LAL method. Suitable for in vivo use.
