This recombinant monoclonal antibody is a research-grade biosimilar to DF003, designed to specifically recognize TNFRSF9 (Tumor Necrosis Factor Receptor Superfamily Member 9), also known as 4-1BB or CD137. TNFRSF9 is an inducible costimulatory receptor expressed primarily on activated T cells, NK cells, and certain antigen-presenting cells. Upon binding to its ligand 4-1BBL, TNFRSF9 delivers critical signals that enhance T cell proliferation, cytokine production, and survival, playing a pivotal role in adaptive immune responses. This receptor has emerged as an important target in cancer immunotherapy research and autoimmune disease studies, as its activation can promote anti-tumor immunity while its dysregulation has been implicated in inflammatory conditions.
As a biosimilar to the reference antibody DF003, this product provides researchers with a reliable tool for investigating TNFRSF9 biology and immune checkpoint mechanisms. It is suitable for studies exploring T cell activation pathways, tumor immunology, and therapeutic antibody development. This antibody enables consistent experimental results in various research settings focused on understanding immune regulation and developing novel immunotherapeutic strategies.
