Recombinant human 4-1BB Ligand/TNFSF9 protein
4-1BB ligand is a type 2 transmembrane glycoprotein belonging to the TNF superfamily. 4-1BBL is expressed by activated B cells, macrophages, dendritic cells, activated T cells, neurons and astrocytes. The interaction of 4-1BB with 4-1BBL strongly regulates immunity and has been proposed to preferentially control T cell responses based on studies in various murine models of cancer, infectious disease and autoimmune disease. Recombinant human 4-1BB ligand, fused to His-tag at N-terminus, was expressed in E. coli and purified by using conventional chromatography.
