This recombinant monoclonal antibody is a research-grade biosimilar to FB-102, designed to specifically recognize IL2RB (Interleukin-2 Receptor Beta chain, also known as CD122). IL2RB is a crucial component of the intermediate-affinity IL-2 receptor complex, primarily expressed on T cells, NK cells, and certain regulatory T cell subsets. This receptor subunit plays an essential role in immune cell proliferation, differentiation, and survival by mediating IL-2 signaling through the JAK-STAT pathway. Dysregulation of IL2RB expression and signaling has been implicated in various immunological disorders, including autoimmune diseases, transplant rejection, and certain hematological malignancies, making it an important target for immunological research.
FB-102 is an agonistic antibody targeting IL-2Rβ, aiming to enhance anti-tumor or anti-viral immune responses by activating immune cells that express "intermediate affinity IL-2 receptors" (composed of IL-2Rβ and γc chains), such as natural killer cells and memory T cells, while avoiding the activation of regulatory T cells. This biosimilar provides researchers with a reliable tool for exploring IL2RB function in various experimental contexts, including investigations of immune regulation, lymphocyte development, and therapeutic strategies targeting the IL-2 pathway. It serves as a valuable reagent for advancing understanding of immune system dynamics and disease mechanisms.
