CD40 ligand has been shown to induce cytokine production and tumoricidal activity in peripheral blood monocytes. It also costimulates proliferation of activated T-cells and this is accompanied by the production of IFN-gamma, TNF-alpha, and IL2. Recombinant Human CD40L produced in E.coli is a non-glycosylated, Polypeptide chain containing 149 amino acids and having a molecular mass of 16,308 Daltons.
