| Interleukin (IL)-4, produced primarily by CD4(+) T cells is an immunomodulatory cytokine, which can inhibit the growth of tumor cells.IL-4 has been known as a Th2 cytokine and can act on B cells, T cells, and monocytes.Interleukin (IL)-4 exhibits antitumor activity in rodent experimental gliomas, which is likely mediated by the actions of IL-4 on a variety of immune cells present in and around the tumor masses. | | | Catalog # | I8426-02A | | Biological Activity | Recombinant Human Interleukin-4 is fully biologically active when compared to standard.
