Recombinant Mouse Interleukin 4 (IL4) is a bioactive protein intended for use in cell culture applications. IL4 promotes the proliferation and differentiation of activated B cells. In addition, IL4 up-regulates class II MHC antigen expression and IgE receptors.
• High purity—no interference from other proteins or contaminants • High biological activity—more results with less protein • Proven compatibility—Gibco® proteins bioassayed with Gibco® media
High Purity Recombinant Bioactive Protein Recombinant Mouse Interleukin 4 is one of more than 250 Gibco® recombinant proteins available from Life Technologies. To help ensure Gibco® growth factors are of the highest quality, each protein is analyzed for purity along with structural homogeneity to ensure a biologically active protein.
High Biological Activity In-house activity testing of Gibco® Recombinant Proteins includes cell proliferation, cytotoxicity, chemotaxis, calcium flux, secondary cytokine up-regulation,
