Recombinant Human 4-1BB Ligand Protein Package Size:50μg √ Lyophilized powder: Stable forDescription The recombinant human 4 1BB Ligand Fc fusion protein is a functional dimeric immunomodulator produced in HEK 293 expression systems, featuring a C terminal human IgG1 Fc domain to enhance structural stability and receptor clustering efficiency. As a TNF superfamily member (TNFSF9 CD137L), it activates NF B and MAPK signaling pathways through binding to 4 1BB (CD137 TNFRSF9) on T cells, delivering critical costimulatory signals that drive T
