| Product Description | Recombinant Biotinylated Human CD40/TNFRSF5 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Glu21-Arg193. |
Product Background |
CD40 is a costimulatory protein found on antigen presenting cells and is required for their activation. The binding of CD154 (CD40L) on TH cells to CD40 activates antigen presenting cells and induces a variety of downstream effects.CD40 molecule is a potential target for cancer immunotherapy. There are number of completed and ongoing clinical trials where agonistic anti-CD40 monoclonal antibodies are employed to activate an anti-tumor T cell response via activation of dendritic cells. |
