人白介素-13|Human IL-13

Synonyms :

NC300 (Human) P600 (Murine)

Description :

IL-13 is an immunoregulatory cytokine produced primarily by activated Th2 cells, and also by mast cells and NK cells. Targeted deletion of IL-13 in mice resulted in impaired Th2 cell development and indicated an important role for IL-13 in the expulsion of gastrointestinal parasites. IL-13 exerts anti-inflammatory effects on monocytes and macrophages and it inhibits the expression of inflammatory cytokines such as IL-1β, TNF-α, IL-6 and IL-8. IL-13 has also been shown to enhance B cell proliferation and to induce isotype switching resulting in increased production of IgE. Blocking of IL-13 activity inhibits the pathophysiology of asthma. Human and murine IL-13 is cross-species reactive. Recombinant human IL-13 is a 12.5 kDa protein consisting of 114 amino acid residues.

Stability :

The lyophilized protein is stable for at least 2 years from date of receipt at -20⁰C. Reconstituted IL-13 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20⁰C. Avoid repeated freeze/thaw cycles.

Purity :

Greater than 98% by SDS-PAGE gel and HPLC analyses.

Endotoxin Level :

Endotoxin level is less than 0.1 ng per µg (1EU/µg).

Biological Activity :

The ED₅₀ as determined by the dose-dependent proliferation of TF-1 cells was ≤ 1.0 ng/ml, corresponding to a specific activity of ≥ 1 x 10⁶ units/mg.
