Recombinant Mouse Interleukin-4 is a pleiotropic cytokine regulates diverse T and B cell responses including cell proliferation, survival, and gene expression. It is produced by mast cells, activated T cells and bone marrow stromal cells. IL-4 regulates the differentiation of native CD4+ T cells (Th0 cells) into helper Th2 cells, and regulates the immunoglobulin class switching to the IgG1 and IgE isotypes. IL-4 also plays a major role in inflammation response and wound repair via activation of macrophage into M2 cells.
ED50 < 2 ng/ml, measured in a cell proliferation assay using murine HT-2 cells, corresponding to a specific activity of >5 x 105units/mg.

例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
