Descrizione

General description

CD40, a member of the TNF receptor superfamily, 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.
Recombinant human soluble CD40 ligand is a 16.3 kDa protein containing 149 amino acid residues comprising the receptor binding TNF-like domain of CD40L.

Product Source: Protein is expressed in E.coli.
The protein is manufactured without the use of any animal products/reagents and is considered Animal-Free and can be used in protocols where possible transmisson of animal viruses and contamination must be avoided.
