Recombinant Human Interleukin 4, His-tagged

Cat. No.: IL4-137H
Product Overview: Recombinant Interleukin-4 protein, fused to His-tag at N-terminus, was expressed inE.coliand was purified by conventional chromatography techniques, after refolding of theisolated inclusion bodies in a renaturation buffer. MW = 17.2kDa (150aa).
Description: Interleukin-4 (IL-4) is a pleiotropic cytokine that has many biological roles, including the stimulation of activated B-cell and T-cell proliferation, and the differentiation of naïve helper T-cell to Th2 cells. Interleukin-4 is a co-stimulator of DNA-synthesis and is induces the expression of class II MHC molecules on resting B-cells. It also enhances both secretion and cell surface expression of IgE and IgG1.
Source: E.coli.
