Background: Mouse interleukin 13 (mIL-13) is a pleiotropic cytokine produced by activated Th2 cells. IL-13 induces B cell proliferation and immunoglobin production. It contains a four helical bundle with two internal disulfide bonds. Mouse IL13 shares 58% sequence identity with human protein and exhibits cross-species activity. IL13 signals via receptor IL13R (type2, IL4R) and activates STAT-6. IL13 initially binds IL-13Rα1 with low affinity and triggers association of IL4Rα, generating a high affinity heterodimeric receptor IL13R and eliciting downstream signals. IL13 also binds IL-13Rα2 with high affinity, which plays a role in a negative feedback system of IL13 signaling. IL13 is an important mediator of allergic inflammation and disease.

Concentration:

Activity: Measure by its ability to induce TF-1 cells proliferation. The ED₅₀ for this effect is <4 ng/mL.The specific activity of recombinant mouse IL-13 is > 2.5 x 10⁵ IU/mg.

Sequence: Pro22-Phe131

Purity: > 95 % as determined by reducing SDS-PAGE.

Formulation: Lyophilized from sterile PBS, pH 7.4.
Normally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.

Reconstitution: Please refer to the printed manual for detailed information.

Endotoxin: < 0.1 EU per μg of the protein as determined by the LAL method.

Calculated MW: 13.1 kDa

ObservedMW: 11 kDa
