背景说明： Interleukin-4 (IL-4) is a pleiotropic cytokine that regulates diverse T and B cell responses including cell proliferation，survival and gene expression.IL-4 is produced by mast cells，T cells，and bone marrow stromal cells.IL-4 regulates the differentiation of naive CD4+ T cells into helper Th2 cells，characterized by their cytokine-secretion profile that includes secretion of IL-4，IL-5，IL-6，IL-10，and IL-13，which favor a humoral immune response.Another dominant function of IL-4 is the regulation of immunoglobulin class switching to the IgG1 and IgE isotypes.Excessive IL-4 production by Th2 cells has been associated with elevated IgE production and allergic response.

溶剂： Always centrifuge tubes before opening.Do not mix by vortex or pipetting.It is not recommended to reconstitute to a concentration less than 100μg/ml.Dissolve the lyophilized protein in distilled water.Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
内毒素： Less than 0.1 ng/ug(1 EU/ug)as determined by LAL test.

Recombinant Human Interleukin-4 is produced by our Mammalian expression system and the target gene encoding His25-Ser153 is expressed.
