Cat. No.:
Cd40-4981M
Product Overview:
Recombinant Mouse Cd40 was expressed in E.coli and purified by using conventional chromatography techniques.
Description:
CD40, a member of the TNF receptor family, is a cell surface protein expressed on B cells, dendritic cells, monocytes, thymic epithelial cells and, at low levels, on T cells. Signaling though CD40 plays an important role in the proliferation and differentiation of B cells, and is critical for immunoglobulin (Ig) class switching. The membrane-anchored CD40-Ligand is expressed almost exclusively on activated CD4+ T lymphocytes. Failure to express CD40L leads to "immunodeficiency with hyper-IgM", a disease characterized by failure to produce IgG, IgA and IgE. The soluble form of CD40L is an 18 kDa protein comprising the entire TNF homologous region of CD40L and is generated in vivo by an intracellular proteolytic processing of the full length CD40L.

Applications:
Numerous applications are possible with this product and should be tested by the end user under their own laboratory conditions
Endotoxin Levels:
Endotoxin level is less than 0.1 ng per ug (1 EU/ug).
Bioactivity:
Determined by its ability to induce TNF-alpha and MIP-1 alpha production by Mouse splenocytes. The expected ED50 for this effect is <0.1 ug/ml.
