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.
The ED50 as determined by the dose-dependant prolifiration of Murine HT-2 cells is less then 2 ng/ml, corresponding to a Specific Activity of > 5 × 105IU/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。
