Product Details


ALRH, BHR1, NC 30, Interleukin 13 (Trehalose).


Description of Human IL-13

Recombinant human IL-13 is a single, non-glycosylated polypeptide chain containing 112 amino acids with a molecular mass of 12 kDa. References show cross reactivity with Mouse, Monkey and Pig. IL13 is an immunoregulatory cytokine produced primarily by activated Th2 cells. IL-13 is involved in several stages of B-cell maturation and differentiation. It up-regulates CD23 and MHC class II expression, and promotes IgE isotype switching of B cells. 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. It shares many properties with IL-4.


Biological Activity

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



We recommend a quick spin followed by reconstitution in sterile Water at a concentration of 0.1 mg/ml, which can then be further diluted into other aqueous or buffered solutions.



The lyophilized protein is stable for at least 1 year from date of receipt if stored at -20°C to -80°C. Reconstituted IL-13 should be stored at 4°C if entire vial will be used within 1-2 weeks. It is stable for least 3 months when stored in working aliquots with a carrier protein at -20°C. Please avoid repeated freeze-thaw cycles.
