Overview
Product name Recombinant Human IL-4 Protein Catalog No. RP02506 Description Recombinant Human IL-4 Protein is produced by Escherichia coli expression system. The target protein is expressed with sequence of Human IL-4 fused with polyhistidine tag at the C-terminus Bio-Activity Measured by its ability to inhibit TF-1 cells proliferation. The ED50 for this effect is <0.2 ng/mL. The specific activity of recombinant human IL-4 is approximately >2.8x 107 IU/mg. Purity > 98% by SDS-PAGE. Endotoxin <0.1EU/ug Formulation Lyophilized from a 0.22 μm filtered solution of PBS, pH 8.0. Species Human Background
The interleukin 4 (IL4, IL-4) is a cytokine that induces differentiation of naive helper T cells (Th0 cells) to Th2 cells. Upon activation by IL-4, Th2 cells subsequently produce additional IL-4 in a positive feedback loop. The cell that initially produces IL-4, thus inducing Th2 differentiation, has not been identified, but recent studies suggest that basophils may be the effector cell. It is closely related and has functions similar to Interleukin 13.Product information
