Interleukin 4, 25-153 Aa Active Protein

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. Recombinant Interleukin-4 protein, fused to His-tag at N-terminus, was expressed in E. coli and was purified by conventional chromatography techniques, after refolding of the isolated inclusion bodies in a renaturation buffer.

Small volumes of Interleukin 4, 25-153 aa active protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
