Interleukin-13 (IL-13) is an immunomodulatory cytokine produced primarily by activated Th2 cells, as well as mast cells and NK cells.IL-13 has anti-inflammatory effects on monocytes and macrophages and inhibits the expression of inflammatory cytokines such as IL-1β, TNF-α, IL-6, and IL-8.IL-13 can also enhance B cell proliferation and induce isotype conversion, thereby increasing IgE production. This recombinant human IL-13 is supplied as Lyophilized powder with high activity, high purity, low endotoxin, and NO labeling.

The ED50 ≤1.0ng/ml，corresponding to a specific activity of ≥1×106 U/mg. Formulation Lyophilized from a 0.22 μm-filtered solution containing PBS, 5% mannitoland 0.01% Tween 80, pH 7.4 Appearance Lyophilized powder Shipping and Storage -25 ~ -15 ° C storage, from the date of receipt of goods, the expiration date of 1 year. After re-solution, store at 2 ~8 °C, 7-10 days expiration date. After re-dissolution, -85 ~ -65 ° C storage, 6 months expiration date. Compounding method Use NO bacterial deionized water to reconstitute lyophilized proteins. It is recommended that proteins be divided for first use to avoid repeated freeze-thawing.
