Recombinant Human Interleukin 13 (IL13) is a bioactive protein intended for use in cell culture applications. IL13 down-regulates macrophage produced cytokines such as TNF-α, IL-1, IL-6, IL-8, and IL-12 in response to LPS challenge or IFN-γ. IL13 induces monocyte differentiation and also induces B cell differentiation and proliferation.

• 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 Human Interleukin 13 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, induction of surface antigen expression, antiviral, and protease assays. Recombinant Human Interleukin 13 (IL13) specific activity is determined by the dose dependent proliferation of human TF-1 cells.

Proven Compatibility
Gibco® proteins are bioassayed with Gibco® media. Since 1962, Gibco® has been the consistent provider of high quality media, reagents, and sera for reliable cell culture.
