Cat. No.	Z300095
Name	Recombinant Rat IL13
Description	Mouse IL-13 is produced primarily by activated Th2 cells. Human IL-13 is expressed in activated T helper cells (resembling Th0, Th1, Th2), and T cells expressing CD8. The alpha chain of the IL-13 receptor has weak binding activity for IL-13. High affinity receptors are formed when the receptor alpha chains of IL-13 and IL-4 receptors are coexpressed. The receptors for IL-3 and IL-4 share a component, a common gamma subunit that is found also in the IL-2 receptor. Different IL-13 receptor structures have been shown to exist on various cell types and the IL-13 receptor may share more than one component with IL-4 receptor. IL-13 down-modulates macrophage activity, reducing the production of pro-inflammatory cytokines and chemokines in response to IFN-gamma or bacterial lypopolysaccharides. IL-13 enhances the production of the IL1 receptor antagonist IL-1ra. IL-13 also decreases the production of nitric oxide by activated macrophages, leading to a decrease in parasiticidal activity. IL-13 induces differentiation of human monocytes, enhances survival time in culture, and also induces differentiation and proliferation and isotype switching in B-cells.

Formulation	Recombinant Rat IL-13 was lyophilized from a 0.2 μm filtered PBS solution.
Function	The ED(50) was determined by the dose-dependent proliferation of TF-1 cells was ≤ 2.0 ng/mL, corresponding to a specific activity of ≥ 1.0 x 10^6 units/mg.
Reconstitution	A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Shipping Conditions	This lyophilized protein is shipped at ambient temperature. Cold packs may be used if transit temperatures are elevated. The product remains stable during normal shipping conditions.
Storage	Upon receipt, store lyophilized protein at –70°C for long-term storage. Short-term storage at –20°C is acceptable if necessary. Once reconstituted, store at 2–8°C for up to 1 month, or at –20°C for up to 6 months. Avoid repeated freeze/thaw cycles.
Usage	For research use only. Not for diagnostic or therapeutic use.
Material Citation	If use of this material results in a scientific publication, please cite the material in the following manner: Applied Biological Materials Inc, Cat. No. Z300095

How do I choose the right growth factor for my experiment?

Cell type: Different cells respond to different growth factors. Choose a growth factor that promotes the growth or differentiation of your target cell type.
Desired outcome: Whether you are studying proliferation, differentiation, or survival, different growth factors will promote different cellular behaviors.
Concentration and formulation: Different experiments may require varying concentrations of growth factors.

	What is the shelf life and storage condition of this product?
	The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
